France was the first major Western power to establish formal diplomatic relations with China. On January 27, 1964, China and France established ambassadorial-level diplomatic ties. Since then, the overall development of their relationship has proceeded smoothly, with productive exchanges and cooperation in various fields such as trade, science and technology, culture, education, and tourism. France is China's third-largest trading partner and the third-largest source of actual investment in the European Union, while China is France's top trading partner in Asia and the seventh largest globally. To date, there are 113 pairs of sister cities and provinces between the two countries.
