Abstract: In 2020, Japans total foreign trade fell due to the severe impact of COVID-19, with its bilateral trade with most partners shrinking to varying degrees. However, Sino-Japanese trade recovered steadily and in particular Japans exports to China increased in spite of various negative factors. Chinas share in Japans total exports and imports has increased. Sino-Japanese economic and trade ties are more closely linked both from the supply side and the demand side, and East Asian supply chain becomes even more resilient. In the post COVID-19 era and faced with growing uncertainty of world economy, Sino-Japanese economic and trade cooperation is still of great importance to the economic development of both countries and the stability of regional supply chain and economic development.

Key words: COVID-19, Sino-Japanese bilateral trade, Japans export to China, supply chain
