A U.S. State Department official said on February 9 that the United States will not accept the conclusions of the World Health Organization's (WHO) coronavirus investigation in China and will independently verify the findings. Wang Wenbin, a spokesperson for China's Foreign Ministry, noted that various researchers have indicated that the coronavirus had surfaced in different locations around the world in the second half of 2019. Virus-tracing is a complex scientific issue and should be conducted by global scientists, he added.
