Chinese Ambassador to the US Cui Tiankai said the rumors that the new coronavirus is a biological weapon are nonsense.

"There are people who are saying that these virus are coming from some- some military lab, not of China, maybe in the United States. How- how can we believe all these crazy things?" he told CBS.

According to the ambassador, scientists cannot yet determine where the new type of virus came from.

"It's probably according to some initial outcome of the research, probably coming from some animals. But we have to- to discover more about it," he added.

The envoy admitted that "maybe some people reacted not quickly enough," to the spread of the virus, "but this is- this could happen anywhere, but whenever we find there's some shortcoming."
