At present, the stability and improvement of Sino-Japanese relations have also created good conditions for the improvement of economic relations between the two sides. Japanese companies, in particular, are optimistic about the potential of China-Japan free trade cooperation, and calls for more cooperation from China and Japan are growing. In 2007, China, Japan and South Korea began negotiations for a trilateral investment agreement. The agreement was officially signed in May 2012. In November of that year, the three countries formally began negotiations for a free trade agreement between China and Japan and South Korea. The current bilateral investment agreement between China and Japan came into force in 1989 – relatively early. Although China and Japan have signed free trade agreements with many countries, China and Japan have not established a free trade mechanism due to external factors such as the rigidity of the U.S.-Japan alliance, U.S. strategic suspicions and volatile relations between South Korea and Japan. The governments of China, South Korea and Japan are expected to begin negotiations on a possible trilateral free trade agreement between the three countries in 2012, first concluding bilateral agreements. If China, Japan and South Korea reach a free trade agreement, it would be the third largest free trade area in the world after the U.S.-Mexico-Canada (USMCA) agreement with the European Union.
The three nations have signed a trilateral investment.  An agreement would promote the integration of Asian economies. All of Asia, along with the rest of the world economy, would benefit from their intimate and progressive trade relations.  In the context of enhanced china-Japan relations, the two countries should begin negotiations on an enhanced bilateral investment agreement as soon as possible and begin negotiations for a free trade agreement between China and Japan. In the context of a paralyzed WTO appeal body, China-U.S. The momentum has shifted more and more towards regional and bilateral free trade agreements (FTAs). In this context, China and Japan should seize the opportunity to adapt their approach to deepening economic cooperation. To prevent the United States from being isolated in international trade, China must actively promote trade liberalization and globalization, integrate more into international markets, and forge closer economic ties with more countries. Currently, China is Japan`s largest trading partner and South Korea, and Japan and South Korea are China`s second and third largest trading partners, respectively. At the eighth China-Japan Summit of Heads of State and Government and last year, the heads of state and government of the three parties said they would work hard to achieve a free, fair, non-discriminatory, transparent, predictable and stable business and investment environment, and to keep markets open.
