Looking back on the history of China's policy toward the United States and the development of Sino-US relations over the past 50 years, we can see that there are both sharp opposition and sincere cooperation between the two sides. After the Cold War, Sino-US relations experienced many ups and downs and crises, but they did not break down, but deepened. The underlying reason is that China and the United States have many strategic interests in common. The United States is the largest developed country in the world, and China is the largest developing country. Both countries have an important influence on the development of the situation in Asia and the world. Under the new international situation, China and the United States share the same interests on many major global and regional issues and have a broad basis for cooperation. The prospect of Sino-US economic cooperation is even more important. Therefore, looking forward to Sino-US relations in the 2nd/Kloc-0th century, we have reason to be cautiously optimistic. Of course, the negative factors affecting bilateral relations can not be ignored. Such as human rights issues, trade issues, arms sales issues and * * *, among which * * * is related to China's * * and territorial integrity, which is the biggest obstacle to the improvement and development of Sino-US relations, and also the most sensitive issue that easily leads to direct conflicts between China and the United States. However, as long as China and the United States can handle Sino-US relations from a historical perspective, they should examine and handle the issue of * * * on the basis of Three Joint Communiqués.

Sino-US relations are one of the most important bilateral relations in the world today. Historically, there are many factors that affect Sino-US relations, such as international structure, economy and ideology, geopolitics and national interests, and policies to deal with bilateral relations. Among them, the policy of handling bilateral relations has a decisive position and influence in Sino-US relations. Throughout the 1970s, history and international relations have been used.

This paper analyzes the origin, change and development of China's policy towards the United States in different periods and its influence on Sino-US relations by using the method of discipline infiltration.

Stabilizing relations with the United States is the key to China's diplomacy. In recent years, there have been more and more cooperative relations between China and the United States. However, this does not mean that the development of Sino-US relations is becoming more and more harmonious. The United States is the largest developed country, occupying the center of power on the world stage. Since the founding of China, the United States has been trying to contain China in various ways, trying to hinder China's economic development through economic, military and diplomatic means. The reason is not difficult to understand. Especially in recent years, China's economic growth rate has shocked other countries, while China itself has a huge market. It has also become a favorable platform for China's economic development. On such a platform envied by many countries, it is an indisputable fact that China's economy will continue to grow at a high speed. With the economic growth, China's military and technological level is also advancing by leaps and bounds. All this forces the United States to regard China as a strong opponent that hinders it from achieving global hegemony. Moreover, in the * *, although the United States has not explicitly stated that Taiwan Province Province will be included in the joint defense of the United States and Japan, it is not difficult to see from its vague description that China, Taiwan Province Province and even Chinese mainland have long been the land that the United States has been spying on. With regard to Sino-US relations, we should adhere to the framework of the three joint communiques and seek stable and high-speed development space for our economy under the current international situation. China and the United States have close economic and trade relations and share common interests in many aspects. Sino-US relations are complicated and must be handled well. Much of China's diplomatic work revolves around this issue.

We should first see and understand the following points:

The opportunity of 1 comes from the international background of globalization, and the United States hopes that China will rise.

The two sides have both intersections and differences on security concerns.

It is not that the United States no longer regards China as a potential rival.

The United States must make a choice on the issue of "unification and independence" of Taiwan Province Province.

Review the history and analyze China's current policy towards the United States.

"Change" and "unchanged" are two aspects of the unity of opposites in China's diplomatic development in the past 50 years. On the one hand, with the changes in the international situation, China's diplomacy has undergone several major strategic adjustments; On the other hand, an independent foreign policy of peace runs through. The basic content of China's diplomacy is constantly enriched, developed and perfected in this constant change, which shows the unique and rich connotation and style of China's diplomacy in different periods in different ways.

"Change" is the requirement and expression of keeping pace with the times, and it is also the need to better seek national interests in different domestic and international environments. And "unchanged" includes two aspects: one is the part of conscious inheritance, which is characterized by continuity; The other part is unwilling to inherit and wants to change. However, due to different reasons, historical policies have a great influence on the psychology of decision-makers or the public, which makes the existing policies intentionally or unintentionally maintain some contents, declarations, trends or tendencies of the original policies and show the inertia of foreign policy. "Change" highlights the characteristics of China's diplomacy, while "unchanged" becomes a negative factor that restricts and influences China's diplomacy in many aspects.

The situation has changed, the policy is not the original policy, and the aid is very different from the past. However, China's foreign policy declaration still regards the Eight Principles as the guiding ideology of China's foreign aid. In fact, this is also
