On March 13, 2018, US Secretary of State Rex Tillerson said: “There is still much to be done to have a clear vision of the nature of our future relationship with China on how we will deal with each other over the next fifty years and ensure a period of prosperity for all our peoples, free from conflict between two very powerful nations.  While U.S. businesses and farmers welcome these commitments, China only agrees to make purchases for the next two years and remains vague about what will happen next. The agreement states that countries “project that the process” of increased purchases will continue until 2025. The shopping list also leaves a few questions unanswered: what happens to China`s existing contracts with other countries for products such as soybeans? Will purchases distort commodity markets? The Reagan administration gave Taiwan the “six assurances,” including a commitment that it would abide by Taiwan`s Relations Law, that it would not mediate between Taiwan and China, and that it did not have a set date to end arms sales to Taiwan. In August 1982, the Reagan administration signed a third joint communiqué with the People`s Republic of China on the normalization of relations. It reaffirms the United States` commitment to its one-China policy. Although Ronald Reagan supported stronger relations with Taiwan during his presidential campaign, his government was working to improve relations between Beijing and Washington at the height of U.S. concern over Soviet expansionism. President Reagan visited China in April 1984 and in June the U.S. government authorized Beijing to purchase U.S. military equipment.
On April 1, 2018, China imposed criminal tariffs on 128 categories of U.S. products in retaliation for the Trump administration`s national security taxes on steel and aluminum imports the previous month. The Chinese government`s reaction is measured and affects annual trade by $3 billion, or about 2 percent of U.S. merchandise exports to China. By the end of September 2018, the Trump administration had introduced tariffs (a 25% tax increase) on US$250 billion of Chinese goods to compensate for the trade imbalance between the two countries. Deputy Prime Minister Deng Xiaoping`s visit to Washington in January 1979 opened a series of important and high-level exchanges that continued until the spring of 1989. .
