What is the point of this agreement?
I think both parties know exactly what the aim of any chip/material bans are.
From the US's side it's to ensure that the Uyghur Muslims have religious freedom and are not oppressed in any way and to ensure all Chinese companies do business in a fair and open manner and are not associated in any way with the Chinese Government. Also to let US companies participate in the Chinese market in a fair and open manner.
From the Chinese side, any measures they take are pretty much purely retaliatory in nature and all they're doing is making life more difficult for the world until they get taken over as the 51st state - oops - that the UK - I mean 52nd ...
Seriously speaking for a moment - looking at the bigger picture, I'm sure the end game of this financial and technological end game is :
a) For the US isolationist policies - a trend which started before WW2 - to continue to come to fruition in the form of full self reliance
b) For sufficient financial disconnection to take place with China to place them on the Sanctioned Countries list
What the US and West doesn't realise is that the countries they are now moving their manufacturing bases to are either ex colonies or are fully aware of what Western power looks like if you're at the wrong end of it - so whilst it may all be smiles and pancakes on the top level, underneath they will be pursuing their own agendas - but with a smile and bow.
