Their behavior toward their own people is increasingly horrid...not sure there is a whole helluva lot we can do about it other than object loudly and shame them.
Trump has pretty much destroyed any leverage we might have had with China, because he insisted on acting alone. We needed to coordinate with Europe, Japan, South Korea, etc...instead we pulled out of the TPP and alienated everyone. You know, like great grand strategy.
And China is not "using the pandemic." That's asinine.
