Mark Landler of NYT provides the background of the relationship with China and Taiwan during the Reagan administration. Reagan criticized the decision to abrogate recognition of Taiwan as a candidate and in 1982 pushed for Six Assurances, one of which was the assertion that the U.S. did not formally recognize Chinese sovereignty over Taiwan. Mr. Trump told a news channel that he doesn't see why the U.S. is bound by a One China policy, and that this would have to be part of a deal that included trade, and solving problems related to North Korea, and the South China Sea island fortifications.
