China said Sunday that relations with the United States were "on the brink of a new Cold War", fuelled in part by tensions over the coronavirus pandemic, as Muslims around the world celebrated a muted end to the holy month of Ramadan. Foreign Minister Wang Yi said Washington had been infected by a "political virus" compelling figures there to continually attack China, but offered an olive branch by saying the country would be open to an international effort to find the coronavirus source. "It has come to our attention that some political forces in the US are taking China-US relations hostage and pushing our two countries to the brink of a new Cold War," he told reporters during a press conference at China's week-long annual parliament session.
