With the in-depth development of Sino-US relations, old problems and new contradictions between the two countries have become increasingly prominent. However, the existence of these problems should not be regarded as an obstacle to the construction of a new type of relationship between China and the United States, but as a driving force for the construction of a new type of relationship between China and the United States. What is "new" in Sino-US relations? This is reflected in the new actors, that is, China is not a traditional rising country in the historical sense, and the United States is not a traditional defending country. China does not seek to challenge the current international order, but becomes a participant and contributor to the construction and improvement of the international system; The United States does not seek to contain the development of China, but to create a more inclusive, open, representative, legitimate, fair and authoritative international system. Secondly, it is reflected in the current new international situation. With the deepening of economic globalization, China and the United States have formed a highly dependent relationship of "you have me" and "I have you". China and the United States are each other's second largest trading partners. In 20 12, the trade volume between China and the United States reached a record high, reaching nearly $500 billion. The United States has become China's largest export market and one of China's largest sources of foreign investment. Cultural diversity and social informatization have continued to advance, and deep-seated and multi-field exchanges between China and the United States have been significantly strengthened; International security faces complex and diverse challenges, and China and the United States cannot deal with them alone, nor can they be immune to them. Therefore, China and the United States not only have close interests, but also have unshirkable responsibilities. It is precisely because China and the United States have established the same sense of interests and the same sense of human destiny that the construction of a new-type relationship between China and the United States has the basic conditions.
