Résumé
China and the U.S. have the biggest markets in the world. They both established diplomatic links in 1979 and the bilateral trade was developed swiftly just after China joined the United Nations Organization (UNO) in 1971. America is the Chinese top one export market and the most significant source of foreign investment. However, the main worldwide economic event in 2018 was the Sino-U.S. trade war. In March 2018, the U.S. threatened to levy high duties on Chinese imports. The equivocal shift of import and export of the Sino-US trade relations were distinctively caught in China's trade surplus with the United States, which brought divergence to the trade relations. Consequently, the Sino-U.S. trade imbalance was the main reason behind why Trump incited the trade war. This paper actually analytically discusses the phenomenon of Sino-U.S. trade war as it is considered as a test case for the new American President Joe Biden.
