If the answer is as simple as that, why did China not expose the US?
Sometimes we should just stop copypasting anything that is said in the net.
Btw, the US also finances research labs in Kenya. These too are bio labs and does not mean they mean evil for mankind or for the country. Lots of high skilled Kenyans working in those labs and am sure they are not complaining.
Reason they refused is because US being left out yet they know. Financed gain of function labs.
