The Chinese foreign ministry said Wednesday that the US should stop thinking he can use tariffs as a weapon to coerce other countries. That's after US President Donald Trump a threatened new tariffs last week, blaming Beijing for the Corona vast crisis. Spokeswoman Hua Chunying said accusations that China deliberately spread the virus are baseless. She urged the U.S. to stop shifting responsibilities. Hua also said that China will expand funding to support the UN initiative to speed up the development of vaccines and treatment for Covid-19.
