Before the early Qing Dynasty, Sino-US relations were not very close and trade was not very big. In the late Qing Dynasty, the United States began to invade China. With the development of the first and second industrial revolutions, the strength of the United States has advanced by leaps and bounds. At the same time, China's closed-door policy also made China decline, and the strength contrast between China and the United States became more and more disparity. The capitalist United States has also stepped up its aggression against China, which is not only reflected in politics, but also in economy. After the founding of New China, the United States took a hostile attitude towards New China and isolated China on the international stage. The weak new China struggled to grow up in the environment at that time! From 65438 to 0972, "ping pong diplomacy" was a new beginning of Sino-US relations. Later, Nixon's visit to China began a historic page in the normalization of Sino-US relations. 1979, China and the United States established diplomatic relations! At this point, the normalization of Sino-US relations began. Today, the United States looks at China's strength and fears that one day China will threaten its position in the international arena. So generally speaking, the United States is now adopting a comprehensive policy of containing China, including economic and political aspects. The problem of Taiwan Province Province is a good example! However, it is obvious to all that in Sino-US relations, the economic and trade relations between China and the United States are beneficial to both sides, and the trade volume between the two sides is increasing. In addition, Sino-US relations are highly correlated internationally, so the United States has to consider China when considering some policies. In short, in Sino-US relations, although the United States has taken measures to contain China, in some respects, the United States relies on China (Latin American relations are an example); As for China, as we all know, China has always adopted a peaceful foreign policy.
