This is a positive sign by the US.

Reuters: Oct 7 (Reuters) - The Biden administration on Friday published a sweeping set of export controls, including a measure to cut China off from certain semiconductor chips made anywhere in the world with U.S. equipment, vastly expanding its reach in its bid to slow Beijing's technological and military advances.

Shows that there are things that can be done. Way better than Aus's strategy of standing in the middle of the road picking up a few dollar bills whilst waiting to get hit by a truck.

In fact Biden has been pretty good on China - all due to Covid one assumes - coz that's the only thing that's changed between now and the previous cozy relationship the Dems had with the CCP. There must be higher-intel that points to a lab-leak, possibly even deliberate, that has precipitated this pivot away. All the stuff with HK, Taiwan, the Uyghurs - that's been going on for decades and no one cared.
