Enhanced adaptation to salinity stress in lentil seedlings through the use of trehalose-functionalized silica nanoparticles (TSiNPs): Exploring silica-sugar absorption and oxidative balance

Silica nanoparticles (SiNPs) confer better growth and development of plants under salinity stress. Moreover, the surface-functionalization of SiNPs with bioactive molecules is expected to enhance its efficacy. The present study thus aimed to modify the surface of SiNPs, by attaching a bioactive molecule (trehalose) to obtain TSiNPs. The successful surface functionalization was confirmed using FTIR, XRD, and EDS. The spherical shape and amorphous nature of the nanoparticles were confirmed using SEM. The TEM image analysis revealed that the size of SiNPs and TSiNPs ranged between 20-50 nm and 200–250 nm, respectively. A novel bioassay experiment designed to study the release of silica and trehalose from nanoparticles elucidated that the TSiNPs improved the release and uptake of silica. Also, trehalose uptake significantly improved after 72 h of application due to enhanced release of trehalose from TSiNPs. Further, this study also aimed to investigate the potential benefits of SiNPs and TSiNPs in promoting the growth and development of plants under salinity stress. In this context, the nanoparticles were applied to the saline-stressed (0, 200, 300 mM) lentil seedlings for the in-planta experiments. The results revealed that both SiNPs and TSiNPs improved the growth of seedlings (shoot, and root length), ionic balance (K+/Na+ ratio), and osmolyte status (sugars, proline, glycine betaine, trehalose). Additionally, increased antioxidant enzyme activities helped scavenge ROS (H2O2, O2.-) generated in NaCl-stressed seedlings, ultimately improving the membrane integrity (by reducing MDA and EL). However, the TSiNPs exhibited a much-enhanced activity in stress alleviation compared to the SiNPs.

Trade Balance and the COVID-19 Pandemic: The Case of Jordan

This research aimed to study the main determinants of trade deficit in the Jordanian economy for the quarterly periods from 2009 to 2021. Specifically, the study examined the effects of the COVID-19 pandemic on trade balance, in addition to other variables. The methodology for this study used Ordinary Least Square (OLS) method which, after applying the necessary diagnostic tests, was verified as the appropriate method. The main result of this paper shows that the COVID-19 pandemic reduced the trade balance, as expected. However, this result is statistically insignificant since the pandemic would improve the growth of the trade balance (TD) from the imports side but would worsen it from the exports side. The results also found that foreign investment was significant in affecting the trade balance. The implication of these results is that the Jordanian economy is vulnerable to outside shocks due to its openness. The government should adopt export-oriented policy to ensure the sustainability of the trade balance.

Microbial Growth in Shrimp Ponds as Influenced by Monosilicic and Polysilicic Acids

In order to increase shrimp production and minimize detrimental environmental impacts of aquaculture, the maintenance and regulation of the growth and composition of phytoplankton communities and nutritional balance are critical. Silicon (Si) is an essential nutrient for diatoms and other types of microorganisms, but the information about the Si impact on their growth is extremely scarce. Monosilicic and polysilicic acids were tested in several shrimp cultivation systems in Jiangsu Province, China. In pond waters, the concentrations of monosilicic and polysilicic acids were sharply reduced by 36-95% and 35-75%, accordingly, as compared with those in supply water sources. The microbial cell abundance was strongly dependent on monosilicic acid. In laboratory experiments, monosilicic acid added to pond water or probiotic solutions at 1- and 2-mM Si had a significant positive effect on cell abundance. Over three days, the concentrations of monosilicic acid decreased by 81 to 91% in pond water and by 11 to 24% in probiotic solution. In probiotic solutions, the degree of polymerization of silicic acid was more intensive than that in shrimp pond waters. The data obtained demonstrates the importance of systematic studies related to the functions of Si in shrimp aquaculture.

ЗАЛУЧЕННЯ ІНОЗЕМНИХ ІНВЕСТИЦІЙ В ЕКОНОМІКУ УКРАЇНИ В УМОВАХ КРИЗИ

The article is devoted to the study of the issue of encouraging investment in the economy of a country that is conducting active hostilities, finding a balance between stimulating infrastructure and industry, the implementation of plans for economic recovery. The purpose of the article is to analyze foreign direct investment in the economy of Ukraine and the city of Kyiv, to determine the prerequisites for their involvement. It is proved that the process of inflow of foreign direct investment Ukraine's economy is uneven: from the fall in 2020, due to the COVID-19 pandemic, to the growth of FDI balance and foreign direct investment in the pre-crisis period. The economic downturn in the state is accompanied by a decline in investment in industry and other sectors of the economy. It should be noted that the rate of decline in investment processes is higher than the rate of decline in industrial production. One of the most attractive for foreign investment was and remains Kyiv, which accounts for up to 50% of foreign direct investment in the economy of Ukraine. Over the last ten years, the volume of capital investments in the city's economy has more than doubled. Active hostilities have changed the priorities for sectoral investment in favor of industries that address basic human needs: agriculture, construction, infrastructure and processing. In order to be able to invest in the military economy, additional levers are needed in the form of state guarantees of protection against non-military troubles. For post-war recovery, the rate of investment should be about $ 70 billion annually. In this regard, it is necessary to work on centralized planning of economic development and identification of enterprises that need to be restored, create a viable portfolio of attractive investment projects and develop ready-made design solutions for potential foreign investors. The paper proposes directions for improving the investment climate and the level of investment attractiveness of Ukraine due to the redistribution of investment directions, for which balancing investments between infrastructure and industry will prevail; creation of mechanisms to protect the interests of investors; motivation of investment entities to long-term use of investments; stimulating the processes of reinvestment of enterprises at the expense of own and borrowed funds and improving investment legislation and ensuring its stability

The results of therapy of congenital adrenal hyperplasia in children in perm region

Background. Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders. About 90% of all children with CAH have 21-hydroxylase deficiency which is required for the synthesis of glucocorticoids and mineralocorticodes. The salt-wasting form of CAH develops with a deficiency of both types of hormones. This form of CAH results in infant death if not treated, therefore early disease detection and start of treatment are very important.
 Aim of research is to study the clinical features of the course of the disease and evaluate the treatment efficacy of children with salt-wasting form of CAH in the Perm region.
 Materials and methods. We conducted an analysis of the clinical features of the salt-wasting form of CAH in 40 children of the Perm region. To evaluate the treatment efficacy following symptoms were analyzed: salty food craving, hyperpigmentation of skin, hirsutism, delayed or accelerated growth, etc. and parameters of water-electrolytic balance, the level of 17-hydroxyprogesterone, adrenocorticotropic hormone, renin.
 Results and discussion. Despite the modern possibilities of diagnosing and treating CAH, the complete control of the disease cant be achieved in all children. Almost all the children examined had either symptoms of replacement therapy failure or overdose symptoms. Hormonal imbalance disorders were performed by a few children without any symptoms of the disease.
 Conclusion. During our research we concluded that young children often have issues with an overdose of hormonal drugs and frequent occurrence of salt-wasting crises against the background of associated diseases, while for teenagers, problems associated with an insufficient dose of glucocorticoid drugs are relevant. Also, significant difficulties in the treatment of children with CAH are associated with the short action of hydrocortisone. One way to solve these problems is to organize a school for parents of children with CAH. Creating motivation, explaining the principles of treatment and importance of regular taking of drugs, as well as algorithm in medical emergency is an important step in achieving control for the disease.

McClusky’s Theory of Margin and its implications on adult learners in higher education institutions

This paper draws on McClusky’s Theory of Margin which contains elements of life transitions. Adulthood period is one of growth, change and integration of balance between energy needed to engage in learning. There is an increasing participation of adult learners in higher education institutions. This paper determines whether learners complete degree programmes on time, or otherwise, by examining responsibilities, resources required for learning, challenges faced and margin available to learners. This qualitative case study used Accra Learning Centre and adopted homogenous, random and sequential purposive sampling procedures. Fifteen participants participated in the in-depth interview conducted. Thematic, narrative and interpretivist approaches were adapted in analysing data collected. It emerged that adult learners have limitless potentials to learn, yet poor time management, work commitments and financial challenges made it difficult to complete programmes on time. Engagement in multiplicities of responsibilities consumed adult learners’ time and energy to learn. The findings are discussed and recommendations are made.

In articles identified and investigated the main factors inhibiting the increase in freight traffic, identified the main measures to minimize them. The object of study is the economic processes of business entities in their operation under the influence of destabilizing factors. The subject of research are scientific-theoretical and practical aspects of transport management. The study used general and special research methods: the method of critical analysis, scientific abstraction and generalization of scientific experience of modern theoretical research, system-integrated approach. It is noted that the main causes of transport threats to the economic security of enterprises are: reduction of rail transportation due to reduced production of coal, ore, oil and gas condensate, wear and tear of material and technical base; the problem of increasing the volume of road transport due to extremely low quality and low capacity of domestic roads, the limited number of large transport companies and the relatively high cost of transport services due to the high cost of fuel; high cost of transportation by sea, river and air transport due to low renewable material and technical base and neglected infrastructure, especially for river transport; strengthening of external economic risks that affect the partnership relations of enterprises, which arose as a result of the military conflict in Donetsk and Luhansk regions and due to the loss of Crimea; inefficiency of the state policy on development of business, counteraction to corruption and legalization of the proceeds of crime. It is noted that Ukraine’s dependence on car imports is one of the determining factors in the growth of the negative balance in foreign trade in goods and the main one in foreign trade in transport engineering products; as a result of staffing of motor transport enterprises with low-skilled personnel, accidents and injuries on motor transport increase. Emphasis is placed on the need to develop and adopt at the state level a single methodology for minimizing transport threats, taking into account modern challenges, which will reduce the technical and technological lag behind the development of transport infrastructure in Ukraine.

Limit Drainage of Separated Tunnel Based on Ecological Groundwater Table: A Case Study

After the excavation of the tunnel in water‐rich regions, the groundwater is continuously discharged into the tunnel. Excessive discharge will cause the groundwater table to drop, which will destroy the normal growth of vegetation and ecological balance. In order to protect the ecological environment, the key is to develop an effective method to determine the tunnel drainage. In this paper, a method for calculating the limit drainage of the tunnel is proposed based on area‐well method and the concept of ecological groundwater table in ecology and agronomy. Some conclusions are drawn as follows. (1) When the ecological groundwater table is constant, with the increase of groundwater discharge, the drainage influence range of the tunnel decreases, the rainfall supplement quantity Wt within the drainage influence range decreases, and the total groundwater discharge quantity Qt also decreases gradually. Since the decreasing rate of Wt is greater than that of Qt, there is a unit drainage that makes the total groundwater discharge equal to rainfall supplement. (2) A separated tunnel under construction in Fuzhou City is taken as an example; the limit drainage q0 of the separated double tunnel is 0.48 m3/(m·d) considering ecological groundwater table.

PRIORITY FORMATS OF TRADE INTEGRATION OF COUNTRIES

Abstract. The study is devoted to the problem of trade integration of countries, in the context of globalization, the development of foreign trade is one of the main factors in the competitiveness of the national economy. Partnership with the EU is strategic for Ukraine. The aim of the study is to reveal the key characteristics and manifestations of the asymmetric development of trade integration of Ukraine and the EU and to identify priority areas of trade and economic cooperation. The object of the study is the process of trade integration of countries on the example of Ukraine with the EU. Methods, measures and tools of trade and economic cooperation between Ukraine and the EU in the context of integration are the subject of the study. The study is devoted to the characteristics of the partnership between Ukraine and the European Union in the context of the Deep and Comprehensive Free Trade Area (DCFTA), which came into force on September 1, 2017 and is part of the Association Agreement. The dynamics of indicators of Ukraine’s economy development and foreign trade sphere is quantitatively estimated. An analysis of relations between Ukraine and the EU was conducted and it was concluded that the EU is a priority partner of Ukraine, as on average 42% of Ukraine’s goods and services are exported to Europe in recent years. The existing asymmetries of trade and economic integration of Ukraine and the EU, which are manifested in technological disproportion, raw material exports from Ukraine and high-tech imports, a negative balance and the constant growth of the negative trade balance of Ukraine are pointed out. To assess the effectiveness of Ukraine’s trade policy measures in terms of the DCFTA, a gravity model was built, which allowed to state that bilateral trade between the EU and Ukraine is more elastic than the dynamics of economic growth of EU GDP and less elastic than the dynamics of Ukraine’s GDP. The study confirmed that the DCFTA between Ukraine and the EU has already significantly affected the growth of trade turnover between these countries. The main integration opportunities and threats of cooperation between Ukraine and the EU have been identified. The main tools of trade integration are highlighted and the priority goals of trade integration of countries are identified in our study of Ukraine and the EU. Keywords: trade integration, trade policy, DCFTA, FTA, globalization, international trade. Formulas: 2; fig.: 1; tabl.: 4; bibl.: 19.

Delayed neurological maturation is a cause for distress during fetal growth restriction

Theory of fetal programming contributes to a better understanding of the relationship of many human diseases with antenatal period pathology. Regulatory impact of nervous system is of great importance. Fetal growth restriction (FGR) is a convenient model for investigation of the abnormalities of fetal neurodevelopment. Fetal heart rate variability is a well-known approach for fetal autonomic function detection.The aim of the study was to detect several patterns of autonomic nervous regulation in FGR complicated by fetal distress or without fetal distress.Materials and methods. Totally 64 patients at 26–28 weeks of gestation were enrolled. 23 patients had normal fetal growth and were included in the Group I (control). 20 pregnant women with FGR without fetal distress were observed in Group II. 21 patients with FGR and fetal distress were included in Group III. Fetal heart rate variability and conventional cardiotocographic patterns were obtained from the RR-interval time series registered from the maternal abdominal wall via non-invasive fetal electrocardiography.Results. Suppression of the total level of heart rate variability with sympathetic overactivity was found in FGR. The maximal growth of sympathovagal balance was found in GroupIII. Fetal deterioration was associated with an increased quantity of decelerations, reduced level of accelerations, and decreased of short term variations and low term variations. But a decelerative pattern before 26 weeks of gestation was normal. Therefore fetal autonomic malfunction could be a result of persistent neurological immaturity in FGR. The approach based on the monitoring of fetal autonomic maturity in the diagnosing of its well-being should be tested in further studies.Conclusion. Fetal heart rate variability variables and beat-to-beat variations parameters could be the sensitive markers of neurological maturation and good predictors for fetal deterioration.

Баланс фосфору за різних систем удобрення в агроценозі Центрального Лісостепу

Goal. To give a comparative assessment of the balance of phosphorus, and to determine a connection with the productivity of cereals in the short crop rotation for long-term application of organic and organo-mineral fertilizer systems in the Central Forest-Steppe of Ukraine. By-products of crops were used as organic fertilizer at saturation of the crop rotation with the legume. Methods. Studies were carried out in the stationary field experiment in the Cherkasy state agricultural experimental station of NSC «Institute of agriculture of NAAS» in 2011–2019 on the area of 0.75 ha in 5 fields with the seed size of the plot 30 m2, and 4-times repeatability. They used field, laboratory, comparative-calculation, and mathematical methods. Results. At the use of organic fertilizer system, a strong correlation was revealed between the output of f.u. and the main products and the rate of turnover and balance capacity of P2O5: in the first case, the opposite (R=0.65–0.69±0.02; R2=0.42–0.48), in the second — direct (R=0.67–0.85±0.02; R2=0.45–0.72). Compared to the organo-mineral fertilizer system correlation weakened somewhat. Per unit of output of f.u. and the primary product increase of the capacity of the P2O5 balance was in 1.78 and 2.11 times smaller. Between the P2O5 balance capacity and balance capacity of N and CO2 was a direct correlation on the average level: R=0.53±0.02; R2=0.23 for N, and R=0,90±0,03; R2=0,86 — for CO2. Per unit of the capacity growth of balance of phosphorus, they fixed 7.62 kg N and 0.79 tons of CO2, which was significantly higher as compared to the organo-mineral fertilizer system. Conclusions. Assessment of dynamics of yield of grain crops in 2011–2019 had shown the following: in organic fertilizer system the increasing trends were detected in winter wheat and barley; in organo-mineral fertilizer system regression coefficients for the variable degree functions at the cultivation of barley were higher in 1.5–1.8 times, winter wheat — were approaching each other. Grain yields at the use of organic and organo-mineral fertilizer systems of cultivation were decreasing, at the use of organic fertilizer system, the drop in trend was in 1.9 times less.

The Analysis of Saline Soils Formation on Different Continents and Bioclimatic Zones: Regional Aspect

Purpose. To detect patterns of solonetz and solonchak spread according to bioclimatic zones and their global and regional ecological problems. Methods. descriptive, analytical, field method, calculational, statistical, correlational analysis. Results. The given paper mentions the most important milestones in saline soils studies. It is determined, that all kinds of soil salination are found on five continents of the world with the natrium salts being the most influential one. Natrium salts occur as a result of sea water getting into and minerals escaping soil in the past geological eras, as well as, irrigation and drainage. It was calculated, that Australia has the largest area of saline soil (357568 ths. ha.), while Africa has the smallest one (80448 ths. ha.), and the correlation of overall continent area to saline soils area presents the following descending order: Australia (50%) → Northern America (7%) → South America (7%) → Eurasia (6%) [Asia (7%) → Europe (4%)] → Africa (4%, 60% of area consists of deserts and arid regions).The most important role in the process of salination and desalination is played by climate and vegetation. The processes of salination and salinization differ depending on bioclimatic zone, which is reflected in chemical components, physical properties, weathering rind. All of the above-mentioned variables define how fertile the saline soil is. Peculiarity of each bioclimatic zone and the conditions of soil formation influence the composition and properties of saline soils, which can differ within one zone. Most of saline soils are found in tropical and subtropical bioclimatic zones.Decrease of the fertile soil area due to salination is the most important ecological problem. The physico-chemical properties are worsening and the level of humus in soil is decreasing. Saline soils make approximately 600 ths. ha. of Kharkiv oblast area. Samples of cultivable layer of soil from Oleshkivsky and Kahovsky regions were taken, in which there were mainly heavily salinized soils (25-63%), moderately salinized soils (77-76%) and mildly salinized solonchaks (4,44-4,54%). The correlational dependency of saline soils was determined:summary indicator of salinity increases with the growth of pH balance; the amount of humus in soil decreases as the level of pH balance rises, especially in the diapason of 8,3-8,5; the amount of humus decreases as the level of soil salinity increases. Conclusions. It is determined, that all kinds of soil salination are found on five continents of the world with the natrium salts being the most influential one.Most of saline soils are found in tropical and subtropical bioclimatic zones.The discovered correlational patterns will enable us to make operative evaluation of the salinity levels, as well as, substantiate and implement highly effective measures, predict possible changes of main indicators, and improve their ecological condition.

DEVELOPMENT OF EMOTIONAL INTELLIGENCE OF PRIMARY SCHOOL PUPILS

The goal of the article is to substantiating the program of psychological follow-up for the development of the emotional intelligence in primary school pupils in the educational process of primary school and analyzing the results of its empirical approbation. In order to verify the effectiveness of the elaborated program we have conducted a forming experiment and carried out a quantitative and qualitative analysis of the obtained results using the methods of mathematical statistics. 72 pupils (grade 4)were participated in the forming experiment, who were included in the experimental (n=36) andcontrol groups (n=36). It was the same number of boys (18 people) and girls (18 people) in each of them, who had a low and an average levels of emotional intelligence. Diagnostic of the development of emotional intelligence of primary school pupils was carrying out with the help of the questionnaire «EmIn» by D. V. Liusin (Lyusin, 2006). After implementation of the program of psychological follow-up of the development of emotional intelligence in the pupils of the experimental group occurs not only an increase of its general level of the development, but also there are positive changes in its structural components and their indicators. The dynamics of the development of the types of emotional intelligence of primary school pupils after the forming experiment shows, on the one hand, the growth of the internal balance of its structural components, on the other – confirms our assumption about the possibility of its development in general. A developed author's program of psychological follow-up of the development of emotional intelligence of primary school pupils can be used by school psychologists, primary school teachers, parents in order to form the emotional competence of children and ensure the success of pedagogical interaction with pupils.

Migration Outflow in Monotowns of Kemerovo Region Studied by Methods of Mathematical Modelling: Integrated Approach

The article deals with the problem of population migration as a factor affecting the prospects for the development of monotowns in Kemerovo region (by the example of Novokuznetsk - a monotown with a stable social and economic situation). One of the negative trends being observed in the monotowns of Kuzbass and determining their development is the growth of natural population decline and negative migration balance. The authors approach the solution of the problem posed from the standpoint of the mathematical theory of optimal processes. At the first stage, integrated assessments of social and environmental attractiveness of a mono-town for the population are constructed to analyze this problem. To find them, the process under investigation is decomposed and pre-sented as a hierarchical model. In the second stage, the dynamics of change in the resulting integrated assessments - environmental attractiveness, housing conditions, the effectiveness of health care and education system operation - is studied by methods of statistical analysis alongside with the impact produced on them due to changes in municipal budget expenditures of the urban district un-der consideration in various areas of financing: “National issues”, “National economy”, “Education”, “Culture, cinematography”, “Public health”, “Social policy”, “Environmental protection”. Based on the dependencies obtained, a model of optimal control is constructed that allows determining the effective distribution of budgetary funds in order to achieve the most favorable socio-ecological situation in a monotown. The proposed model can be used by mu-nicipal authorities in developing programs for the strategic development of monotowns.

Comparative analysis of abscisic acid levels and expression of abscisic acid-related genes in Scots pine and Norway spruce seedlings under water deficit

Abscisic acid (ABA) is one of the main participants in the regulation of plant responses to water deficiency. Knowledge of the ABA signal transduction pathways in gymnosperms is rather limited, especially in comparison with those in angiosperms. Seedlings of Scots pine and Norway spruce are known for their contrasting behaviour strategies under water deficit. To characterize the possible role of ABA in these differences, ABA dynamics were investigated under conditions of water deficit in seedlings of these two species. The content of ABA and its catabolites was followed in the roots and needles of seedlings of Pinus sylvestris and Picea abies under conditions of polyethylene glycol (PEG)-induced water deficiency (−0.15 and −0.5 MPa) for 10 days. The expression of the main genes for ABA-biosynthetic enzymes was also analysed. ABA showed more pronounced stress-dependent dynamics in pine roots than in spruce roots, whereas in needles, the response was greater for spruce than pine. The ABA increase during drought was mainly due to de novo synthesis and the shift in the balance between ABA synthesis and catabolism towards synthesis. The ABA-glucosyl ester did not serve as a reserve for the release of free ABA under water deficiency. The expression levels of the main ABA biosynthetic genes showed a weak or no correlation with changes in ABA content under water stress, i.e., the ABA content in the seedlings of both species was not directly linked to the transcript levels of the main ABA biosynthetic genes. Less-pronounced stress-induced changes in ABA in pine needles than in spruce needles may be related to pine seedlings having a less conservative strategy of growth and maintenance of water balance under water deficit.

TRADE ECONOMIC COOPERATION OF KOSOVO WITH THE WESTERN BALKAN COUNTRIES

With the rapid development of manufacturing forces, national markets are becoming very small, while the need for economic cooperation between countries is becoming ever greater. Economic and trade cooperation between countries is the only way for small countries to benefit from large markets. Viewed from the aspect of transition countries, this collaboration offers domestic producers the opportunity to link to global chains. For a small and new country like Kosovo, good economic and trade relations with neighboring countries are of great importance. Free trade with the countries of the region is of the utmost importance for Kosovo because it not only allows the import of raw materials and products that are not produced domestically, but it also provides potential markets for its exports. However, we recognize the fact that in terms of carrying out trade activities in relation to other countries, Kosovo faces a continuing problem that is the trade balance deficit as a result of its dependence on imports and as a result of its, in development constraints of exports. Kosovo is the smallest country in the region due to its size, but also by its economic and trade impact in the region. It is characterized by a lack of domestic economic development, namely with lack of the manufacturing sector and industry, and as a result, it can not satisfy domestic demand, which the demand is then forced to cover mainly by imports, by thus affecting the growth of the trade balance deficit.The purpose of this paper is to analyze the trends in Kosovo's foreign trade through various data published by relevant institutions, in order to look at the directions and trends in the development of trade activities with other countries, mainly with the countries of the Western Balkans (Albania, Bosnia and Herzegovina, Macedonia, Montenegro and Serbia) and to seen the importance of this economic and trade cooperation. Based on this database and the comparisons made over the years, conclusions are drawn regarding the current trade conditions between Kosovo and these countries, their economic relations within CEFTA and the EU and their long-term economic orientation. Given the unfavorable trade situation in the region, it is necessary for the Balkan countries to strengthen their friendly bridges and to increase economic cooperation with a view to the mutual development of trade. This will most certainly contribute to an accelerated economic development for these countries as well as to improving the relations of the countries of the region. Creating a good relationship between the countries of the region is also the main goal of CEFTA, which enables the creation of a free trade zone for the Western Balkan countries. The path to prosperity for the Western Balkans depends on the progress of regional and international economic integration by linking with global markets through trade, transport, and investment.
