U.S. President Donald Trump expressed a willingness on Tuesday to work with China or other countries to bring a successful coronavirus vaccine to the United States, despite rising tensions between Beijing and Washington.

"We're willing to work with anybody that is going to get us a good result," Trump said, when asked if the administration would collaborate with China on a vaccine for Americans, whether China is first to develop one or not. ​

The remarks came a day after researchers said a vaccine against the coronavirus developed by China's CanSino Biologics Inc (6185.HK) and China's military research unit appeared to be safe and induced immune responses in most subjects in a closely-watched mid-stage study.
