The United States and China remained at loggerheads Thursday over a UN Security Council draft resolution calling for a 90-day humanitarian pause in conflicts worldwide in the face of the coronavirus pandemic. The stalemate — over a mention of the World Health Organization — leaves little hope of a quick vote as the Security Council struggles to find a response to the global crisis, remaining largely mute since the once-in-a-century pandemic began killing tens of thousands of people and shutting down economies across the world. At a news conference, UN Secretary-General Antonio Guterres deplored the impasse.
