They have signed a non-binding agreement to potentially cooperate on AI supply chains. It's hardly a declaration of fealty, nor does it have any practical impact on the use of Chinese models in the near term. I'd view this more as hedging their bets for the future.
> It's hardly a declaration of fealty
As a European, the way I see it, Europe declared fealty to the US and relinquished its sovereignty a long time ago, sadly.
Also, the way these agreements tend to work is that you agree that you won't source from the 'enemy side' i.e. China. It works this way for NATO and it will work the same way here.
