In terms of science, entry of an enterprise into a foreign market is a problem of internationalization. Investigation of this issue over the past decades has allowed us to form a scientific base, which represents the process of internationalization of a national company as a complex process that includes both organizational and marketing aspects. In particular, success of an entry is ensured by taking into account the needs of foreign customers, as well as passing through a number of stages, accompanied by the identification of peculiarities of the foreign market and the accumulation of experience necessary for promotion on the international market. The entry of Trans-Baikal Territory into the Far Eastern Federal District and the opportunity to use additional benefits for business that has arisen opens up great opportunities for entrepreneurs to create new products, introduce new technologies, reduce costs and, thus, open up prospects for promotion on foreign markets. From the point of view of international business theories, the start of operation in foreign markets should be connected with the markets of neighboring countries. For the manufacturers of Trans-Baikal Territory, China is such a market. At the same time, its attractiveness is determined by a number of market factors. Consideration of these factors makes it necessary to develop an international marketing complex for each exporter. The problem is that most of the exporting enterprises representing small and medium-sized businesses lack experience and financial capabilities to develop an international marketing mix. The article shows the possibilities of solving the problem, taking into account the characteristics of the Chinese market. The most promising areas for the development of international business are the production of agricultural and food products. The national project «International Cooperation and Export» allows using the competitive advantages of the Trans-Baikal producers and provides them with a sufficiently strong position in the future.
