United States President Donald Trump has said that the US was working together closely with China over the coronavirus disease. Donald Trump in a tweet wrote, “Just finished a very good conversation with President Xi of China. Discussed in great detail the CoronaVirus that is ravaging large parts of our Planet. China has been through much & has developed a strong understanding of the Virus. We are working closely together. Much respect!” Just finished a very good conversation with President Xi of China. Discussed in great detail the CoronaVirus that is ravaging large parts of our Planet. China has been through much & has developed a strong understanding of the Virus. We are working closely together. Much respect! — Donald J. Trump (@realDonaldTrump) March 27, 2020 The phone conversation followed a video conference meeting of G-20 leaders during which Xi gave a speech calling for greater international cooperation. The virus was first reported in late December in the Chinese city of Wuhan and has since killed more than 3,200 people in the country. The spread of the virus domestically has since stalled, but China has stepped up efforts to prevent travelers bringing the disease back from overseas by essentially closing borders to foreigners beginning Saturday. “The Chinese side is willing to continue to provide information and experience with the U.S. without reservation,” the report added, noting some provinces, cities and businesses in China are providing the U.S. with medical supplies. “The Chinese side understands the current difficulties of the U.S., and is willing to provide support within (China’s) ability.” It was not immediately clear from the report whether China would give away supplies, or that it just hopes to sell more. China has donated some supplies externally since the crisis began, as well as accept assistance from outside.
