Fortunately, this is of no significant barrier.
It is not a barrier because we, in the US, can ban their hardware anyways, and cause serious economic damage to them anyway.
So it doesn't particularly matter if we use IP law itself, in the courts, against china, when we have other options, such as simply banning their products in this other way.
No we wouldn't. Literally we are commenting in an article, about what I am suggesting is happening.
So the stuff that the article says is already happening, is what I suggested.
Could it go faster? Maybe. But like I said, we are literally commenting on an article, about how US telecoms are being required to replace certain equipment.
To my knowledge this has not previously been used as punishment for theft of trade secrets (Hwawei was sanctioned for doing business in Iran), but the legal mechanism is there.
Put simply, American courts have no authority over Chinese in China, Chinese courts have no authority over Americans in the US, and our courts do not cooperate reciprocally as they do in other countries with alternative diplomatic and legal relations.
