The Six Assurances are six key foreign policy principles of the United States regarding United States–Taiwan relations. They were passed as unilateral U.S. clarifications to the Third Communiqué between the United States and the People's Republic of China in 1982. They were intended to reassure both Taiwan and the United States Congress that the US would continue to support Taiwan even if it had earlier cut formal diplomatic relations. The assurances were originally proposed by the then Kuomintang government of the Republic of China on Taiwan during negotiations between the U.S. and the People's Republic of China. The U.S. Reagan administration agreed to the assurances and informed the United States Congress of them in July 1982. Today, the Six Assurances are part of semiformal guidelines used in conducting relations between the US and Taiwan. The assurances have been generally reaffirmed by successive U.S. administrations. Prior to 2016, they were purely informal, but in 2016, their formal content was adopted by the US House of Representatives in a non-binding resolution, upgrading their status to formal but not directly enforceable.
The August 17 Communiqué, “should not be read to imply that we have agreed to engage in prior consultations with Beijing on arms sales to Taiwan”.
The resolution has been received by the Senate and referred to the Committee on Foreign Relations. In the first version, which was introduced to Congress by Rep. Steve Chabot on October 28, 2015, the Six Assurances were proposed to be:
The United States would not alter its position about the sovereignty of Taiwan which was, that the question was one to be decided peacefully by the Chinese themselves, and would not pressure Taiwan to enter into negotiations with China; and
The United States would not formally recognize Chinese sovereignty over Taiwan.
Reaffirmation
The State Department has reaffirmed the Six Assurances repeatedly. On May 19, 2016, one day before Tsai Ing-wen assumed the Presidency of the Republic of China, U.S. Senators Marco Rubio, a member of the Senate Foreign Relations Committee and Senate Select Committee on Intelligence and Bob Menendez, former chair of the Senate Foreign Relations Committee and co-chair of the Senate Taiwan Caucus, introduced a concurrent resolution reaffirming the Taiwan Relations Act and the “Six Assurances” as cornerstones of United States–Taiwan relations. The Republican Party Platform of the 2016 Republican National Convention mentions the Six Assurances, stating, "We salute the people of Taiwan, with whom we share the values of democracy, human rights, a free market economy, and the rule of law. Our relations will continue to be based upon the provisions of the Taiwan Relations Act, and we affirm the Six Assurances given to Taiwan in 1982 by President Reagan. We oppose any unilateral steps by either side to alter the status quo in the Taiwan Straits on the principle that all issues regarding the island’s future must be resolved peacefully, through dialogue, and be agreeable to the people of Taiwan. If China were to violate those principles, the United States, in accord with the Taiwan Relations Act, will help Taiwan defend itself. We praise efforts by the new government in Taipei to continue constructive relations across the Taiwan Strait and call on China to reciprocate. As a loyal friend of America, Taiwan has merited our strong support, including free trade agreement status, the timely sale of defensive arms including technology to build diesel submarines, and full participation in the World Health Organization, International Civil Aviation Organization, and other multilateral institutions." As of September 2018, the Donald Trump administration "has stated that the U.S.-Taiwan relationship is also 'guided' by 'Six Assurances'".
