At a "later date", Trump will travel to Beijing where negotiations for phase 2 of the trade talks will begin, he writes.

The partial trade agreement between the two major powers, called Phase 1, was concluded in mid-December. Trump said on Christmas Day that it would be signed by him and China's President Xi at a special ceremony, but now it does not appear that Xi will be in the White House. "High representatives of China will be present," Trump writes.

According to the United States, the so-called Phase 1 agreement means, among other things, that China will make extensive purchases of American products and implement unspecified "structural" changes. The United States, for its part, will impose new planned penalties on Chinese goods.

US Trade Representative Robert Lighthizer has previously stated that the 25 percent duty on Chinese goods for $ 250 billion, which has already been introduced, will quadruple. The tariff level on other current Chinese goods, worth about $ 120 billion, is 7.5 percent.
