Marcon is probably done after this term, he is too much trying to play both side and people in France think he simply ignore any domestic issues (hence this trip to China is seen as an extremely unpopular move in France)
He went all out trying to be the dipolmat of the lifetime, but in the end, he can't solve the Russian-Ukraine issue, and he probably not going to solve the China-Taiwan issue, that's why people hate him.
By the way, this is actually what he said
It's stuff like that make people hate him.
