President Trump tweeted on May 5th, that he would impose increased sanctions on China, potentially up to 25% on all products imported from China, if a new trade agreement was not reached, presumably by Friday, May 10th. i The tariffs were imposed and the talks ended on Friday afternoon. In addition to the tariffs, the Chinese were refusing to go along with the US positions on issues like forced technology transfers (in exchange for doing business in China) and other enforcement tools that the US is seeking. The only surprise here is that the administration is surprised.
