Trump was not a wuss so he would have informed the Chinese that lack of cooperation will be considered an admission of guilt and that heavy, heavy sanctions and maybe worse would follow. Biden is asking nicely and then when they tell him to piss off he'll say 'well, what can I do? Lets just move on'. And Hunter gets a new company going in China a week later with some large and mysterious infusion of funding.
My granddaughter worked in a lab here in the USA and still does. She says it's awful because the Chinese will speak Chinese and English only when absolutely necessary. She also said...everyone of them is stinkin' wealthy.
