The United States has terminated its extradition agreement with Hong Kong, the latest step in putting pressure on Beijing after the imposition of a controversial national security law on the former British territory. The Reagan administration gave Taiwan the „Six Insurance“ and the commitments it would meet under the Taiwan Relations Act, that it would not mediate between Taiwan and China, and that it did not have a fixed date to stop arms sales to Taiwan. The Reagan administration then signed a third joint communiqué with the People`s Republic of China in August 1982 to normalize relations. It reaffirms the United States` commitment to its one-China policy. Although Ronald Reagan expressed support for 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. concerns about Soviet expansionism. President Reagan visited China in April 1984 and in June, the U.S. administration authorized Beijing to purchase U.S. military equipment.
Differences in security, ideology and development models weigh on Sino-Soviet relations. China`s policy of radical industrialization, known as a great leap forward, led the Soviet Union to withdraw its advisers in 1960. Disagreements culminated in the border conflicts of March 1969.

These agreements cover the surrender of refugees, transfers and convicted prisoners, as well as mutual tax exemptions on international shipping revenues.  The three agreements concern the transfer of refugees and convicted prisoners. They also apply to mutual exemptions on income from international shipping, the department said. In March 2007, China announced an 18 per cent increase in defence spending for 2007, for a total of more than $45 billion. The increase in military spending averages 15% per year between 1990 and 2005. During a 2007 trip to Asia, U.S.
Vice President Dick Cheney said China`s military rearmament was „not in line“ with the country`s stated goal of achieving a „peaceful ascent.“ China says it is increasing spending to better train its soldiers and get higher salaries to „protect national security and territorial integrity.“ In a telephone conversation with Chinese President Xi Jinping, U.S. President Donald J. Trump said he will abide by the one-China policy. After the victory in the presidential elections, Trump broke with the common practice by phoning Taiwanese President Tsai Ing-wen and questioning the United States.
