The next one to flip in EU will probably be France.
In fact it was Macron that started this trend. Back last year when CAI was off and EU and China was doing sanctions on each other Macron was the first to do a sneaky deal directly between France and China, cutting out EU in the process:
For two billion euro investment he showed up personally for the occasion. Afterwards Macron got all that bitch slapping going his way with the cancelled sub deal and so on and he started cowering. But his first breaking of the rank might have given people the idea.
Macron has already said he wants to visit Beijing and he even did that thing where he suggested he and Scholz should go together. This time the germans were clever and said oh no you la don't.
Also this. Belt and Road Initiative needs some cool merchandise like some cool BRI T-shirts and trucker caps. And maybe a BRI rap song
