Well the US can't organize anything economically against China without Europe. So just as long as Europe doesn't go along with the US, that is a huge roadblock against the US.
The same people who think China is dependant on australian metallurgic coal for power supplies are the same people who believe the 3 gorges dam broke and flooded and that china needs to import indian rice to survive.
And also,
Rebuttal for those who say that China gave up heaps for the status quo with Europe:
This deal allows for Chinese investment into european companies, companies i presume like ASML or airbus.
And given the copious amounts of Copium being inhaled by the atlanticist press, i can only presume this REEEing is a Good Thing for China.
If you believe in free trade principles, all you have to do is remain open by yourself.
If the other party chooses to be closed, then they lose out.
It's a hard lesson China learned after all those years of isolation.
That's why Xi keeps saying China will be more and more open. BRI, RCEP, this, and lots of upcoming reforms hopefully.
