Abstract: With the arrival of another summit meeting between China and the United States, the discussion on Sino-US relations has once again entered people's field of vision. Sino-US relations are very good now. The leaders of the two countries made it clear that they would make joint efforts to expand bilateral cooperation and raise the level of cooperation. They are either sincere, intentional or have ulterior motives. China and the United States will jointly meet global challenges and develop positive, cooperative and comprehensive US-China relations for the benefit of the two peoples and the international community. Only by treating Sino-US relations rationally and dialectically can China better stand among the nations in the world. Key words: Sino-US relations, contradictions and common interests, win-win text: For decades, there have been confrontation and relaxation, as well as cooperation and competition between China and the United States, which have withstood the test of international changes, but Sino-US relations have still overcome all kinds of difficulties and obstacles and developed in stormy waves. Contradictions and differences between China and the United States are the fundamental reasons for the United States to contain China, but the existence of common strategic interests is the basis of cooperation between the two countries. Whether the United States will contain or cooperate with China depends largely on the current world where China and the United States share common interests. Under the realistic background that a superpower (the United States) coexists and competes with many powerful countries (Russian, European Union, Japanese, China, etc.). ), political multipolarization and economic globalization are developing together, and hegemonism led by the United States continues to be active in the international arena. Relying on cooperation, containment and prevention together constitute the relationship between big powers. Although there are many contradictions and differences between China and the United States, they also have extensive common interests. 1. Contradictions and differences between China and the United States entered China in the 2nd1century, with rapid economic development, remarkable achievements in domestic construction and more voice in the world. China has changed from a chess player seeking balance among great powers to a chess player who participates in the division of the world pattern and actively realizes his own interests in the undercurrent world political arena. As the only superpower in the world today, the United States is still the undisputed hegemon despite the economic crisis. The rise of China is bound to arouse the vigilance of the United States. However, there is not much geopolitical conflict between China and the United States. Energy and trade are the most likely to cause friction between the two countries, which is the focus of debate between China and the United States in recent years. The issue of Taiwan Province Province is also a time bomb buried between China and the United States. If the issue of Taiwan Province Province is not properly resolved, there will definitely be bad feelings between China and the United States, and it will be impossible to carry out deeper cooperation. China and the United States are interdependent and win-win.

The United States is the largest developed country in the world, and China is the largest developing country. The economic and trade relations between the two countries are mutually beneficial and have great development potential. After China joined the World Trade Organization, Sino-US economic and trade cooperation showed a good momentum of sustained and rapid growth. China now thinks that the United States is the fourth largest trading partner and the United States is China's second largest trading partner. American exports to China create 500,000 high-paying jobs for the United States every year, and China's inexpensive goods save American consumers $20 billion every year. In addition to the positive growth of bilateral trade, the two countries have maintained close consultations and dialogues on economic and financial issues, which shows that Sino-US relations have developed to a state where you have me and I have you. Damage to either party will inevitably lead to damage to the other party. After the "9. 1 1 incident", the United States changed its attitude towards China to a certain extent, and its understanding of no common interests and differences changed greatly. This has provided conditions for the friendly development of Sino-US relations. Although China and the United States have differences in some places, they also have common interests. China and the United States should strive to find a "harmonious but different road." Strengthen cooperation on common interests and seek common ground while reserving differences. Opportunities for the steady development of Sino-US relations Facts have proved that the development of Sino-US relations has brought benefits to the two peoples and promoted world peace and development. In recent years, there has been a positive development momentum in Sino-US relations. China and the United States agreed to jointly promote the development of mutually beneficial and win-win Sino-US economic and trade cooperation. Some differences and frictions can be properly resolved through equal consultation. The outcome of the 17th China-US Joint Economic and Trade Commission held not long ago is an example. The educational cooperation between the two countries in the fields of military affairs, law enforcement, science and technology, culture and education has broad prospects. Dialogue and cooperation in anti-terrorism, nuclear non-proliferation, avian influenza air defense, energy, environmental protection, disaster relief and other important aspects are also in the common interest of both sides. Only by promoting the six-party talks on the Korean Peninsula nuclear issue and continuing to work for the peaceful settlement of the Iranian nuclear issue can world peace be maintained. Seize the good opportunity of the stable development of Sino-US relations, vigorously develop the economic construction of China countries, build a harmonious society with sustainable development in China, and build a harmonious world with lasting peace and common prosperity with all countries in the world. This is an important historical opportunity and an opportunity that conforms to the common interests of people all over the world. Conclusion:

The development of Sino-American relations clearly embodies a famous saying in the diplomatic circles: there are no eternal enemies or friends between countries, only eternal interests! Both China and the United States are serving their own interests, from bitter rivals to threats from the Soviet Union to separation and integration. The past has become history, and Sino-US relations have been advancing slowly in ups and downs. The remembrance of the past is the teacher of the future In the foreseeable future, only by establishing harmonious relations and deepening cooperation between China and the United States can we maximize the interests of the two countries and achieve a win-win situation.
