China’s foreign minister told the U.S. ambassador on Monday that Washington is responsible for the downturn in relations between the two countries and must “reflect deeply” before ties can return to a healthy track, an official said. Qin Gang’s comments follow a suspension of serious dialogue on a range of issues between the world’s largest economies, increasingly at odds over tariffs, attempts by Washington to deprive China of cutting-edge technology, and China’s claims to self-governing Taiwan and large parts of the South and East China Seas. China's Foreign Ministry quoted Qin as telling Ambassador Nicolas Burns that a “series of erroneous words and deeds by the U.S." since a meeting in November between U.S. President Joe Biden and Chinese leader Xi Jinping "have undermined the hard-won positive momentum of Sino-U.S. relations.”
