The Belt and Road Initiative (BRI) was proposed by President Xi Jinping during his visits to Central Asia and Southeast Asia in 2013, advocating for collaborative development with countries along the route. Spanning across the continents of Asia and Europe, the Indian Ocean, and the western Pacific, the BRI involves 64 countries with a total population of over 3 billion and a combined GDP accounting for nearly 20% of the global economy, holding significant strategic importance. Historically, the BRI serves not only as a platform for commercial trade but also as a medium for cultural exchanges among the countries along its route. In reality, embracing cultural diversity aligns with the collaborative development goals of the BRI, promoting cultural and civilizational exchanges among nations, achieving holistic cultural complementarity, and fostering social harmony and development. In recent years, Chinese language education has been included in the educational systems of European, Latin American, and African countries alongside languages such as French, Russian, and Spanish. In the context of increasingly integrated global interests, Chinese language education has gained more attention. To internationalize and diversify Chinese language education, the term Confucius Institute was coined. Drawing on international experience, the Chinese government has established numerous Confucius Institutes and classrooms overseas. Among them, Portugal is one of the European countries with the closest cooperation with China in education, language, and humanities. With the comprehensive development of Sino-Portuguese relations, more opportunities have arisen for Sino-Portuguese language and cultural exchanges, expanding the development prospects of Confucius Institutes. Currently, the four main Confucius Institutes jointly established by major universities in Portugal are: Minho University Confucius Institute, University of Lisbon Confucius Institute, University of Aveiro Confucius Institute, and University of Coimbra Confucius Institute. Each Confucius Institute has its own educational positioning, such as providing basic Chinese language teaching, training Chinese language teachers, improving Chinese language teaching resources, and organizing Chinese cultural exchange activities, providing Portuguese students with a platform for learning Chinese language and culture.
