The essence of this Sino-US trade friction is that the political problem lies in economic differences. Although trade disputes have not yet formally appeared, repeated trade negotiations have increased the complexity and uncertainty of the game between China and the United States. This trade war happened at a critical moment when the recovery of the world economy is weak, the world populism is on the rise, and China's economy may surpass the United States to become the world's largest economy. Many factors are superimposed, and Sino-US trade friction may last for more than ten years.
Looking back at history, the trade war between the United States and Japan lasted for nearly 30 years, and ended when the Japanese real estate price bubble burst in the early 1990s. The United States successfully curbed the momentum of Japan's rise. Since then, Japan has become farther and farther away from the world's largest economy.
