When the Kishida Wenxiong government was established, in the case of tension with China, he explored the path of "cooperation" with China.This is different from the word "(with China) cooperation.The "cooperation with China" of the government of the Sugi Yiwei is similar to the Chinese wording.However, the Kishida government is aware of domestic public opinion, and the pace of relations with China is relatively slow. It was not until 2023 that it improved and improved relations with China.This year, Japan, as the chairman of the United Nations Security Council, and the chairman of the Seventh Kingdom Group (G7), may also realize that it is necessary to add some resources to China and foreign trade.

In the meeting with Chinese President Xi Jinping in November last year, Kishida reached an agreement on building a "constructive and stable Japanese -China relations".This is based on "Japan and China have a broad prospect for cooperation, and also facing many topics and serious concerns, in a very important situation" "Japan and China have a major responsibility for the peace and prosperity of the region and the international community.On the basis of the big country, the agreement will be reached to "the two sides will continue to work hard to implement the consensus of Japan and China."

As a specific cooperation project, in November of last year, in November, it was drafted "Green Economy, which includes environmental protection, energy conservation and emission reduction, and cooperation and national exchanges in medical, nursing, health care and other economic fields."However, the economy as the driving force for cooperation, and there are many topics. For example, when China ’s detention cases to Japan and business people have increased, when the Japanese foreign minister Lin Fang was visiting China to meet the Chinese Foreign Minister Qin Gang, he strongly requested that“ ensure it in China in China to ensure that in ChinaTransparent, foreseeable and fair business environment, and ensuring legified economic activities in terms of security. "At the same time," the Chinese forcibly demanding openness and transfer of technology is becoming stronger and stronger "expressed concerns.The economy between Japan lacks the motivation to promote cooperation.

What is even more noticeable is that at the "16th China -Japan Energy -saving and Environmental Comprehensive Forum" held in February in February, 17 Japanese -Chinese cooperation documents were signed, involving energy conservation, new energy, and low -carbonization., Environmental protection and other fields.It is difficult to determine to how much these projects will be implemented, but from Japan, the Minister of Economic and Industry Nishimura Kangyu, the president of the Japan -China Economic Association Zong Gangzheng, and the leader of the China National Development and Reform Commission, He Lifeng, the assistant to Li Fei, the Minister of Commerce, etc.Participation can show that both sides have shown an attitude of promoting this cooperation.

On the other hand, in the Japanese leader talks in November last year, the two sides also put into use on the hotline of the sea and air contact mechanism as soon as possible to reach an agreement.At the end of March this year, the two governments set up a safe hotline in order to avoid the self -defense team and the PLA's sudden conflict on the maritime.

Japan and China governments have each added military budget.Focusing on the continuous upgrading of world order tensions including Taiwan, the two governments have added opportunities for dialogue and established measures such as the contact mechanism to prevent the incident from expanding and promoting cooperation as much as possible.But the question is that when the relationship is more tense, can these contact mechanisms play a role and can cooperative projects continue to be implemented?If the contact mechanism cannot play a role when the tension is rising, or if the relationship is slightly tension, it immediately interrupts the cooperative relationship, which means that these cooperative relationships and emergency contact mechanisms, etc., rely entirely on the quality of political conditions.

In the future, whether the Japan -China contact mechanism and cooperation project can be decoupled with the tension of the above relations and continue to play a role, it will become an important issue.
