And they revoke the license in US and basal states, isn't it?

Sanctions on Russia, it's in the article

"Russia had been forced to repeatedly establish new supply chains for acquiring chips. As sanctions disrupted existing smuggling routes, it had set up new ones, likening these outcomes to a game of “whack-a-mole”, that was frustrating for both Western governments as well as “supply-chain managers at Russian missile and drone factories”.

The biggest failure in enforcing the controls is not that Russia continues to have some success in smuggling — that’s not a surprise — but that China continues shamelessly to sell Russia so much via normal trade routes."

There is 0 reason for China to care about US sanctions. The US doesn't own China.

Well the US is making them care by punishing China with this move.

Yeah, but if the sanctions cut off Russia <- US import path, but then Russia and China established Russia <- China <- US import path, it makes some sense for the US to cut off the China <- US leg.
