Of all the major Western leaders, Macron is probably the most charismatic.
Even in this thread you can see that effect.
Anyway, I tend to not focus that much to individual leaders and instead prefer to see things from an overall point of view. Leaving Macron aside, France is a vassal territory of the American Empire. That Macron says a couple of good things and signs some business deals with China doesn't change that fact.
The biggest problem China faces is the white-European domination of the world. Just surpassing US in GDP and military power is not going to be enough for China to really create a multipolar world. The world has only one pole, that is the white-european "west" which currently hold 60+ trillion dollar in GDP nominal and more than 55% of the global GDP and most of the world's advanced tech and cultural power.
This is the hegemony that China will have to break, if it wants to create space for itself in this world
So, breaking the western alliance and creating feelings of independence is one of the most important tasks China will have to take. France is the probably the best candidate for this. It still has a lot French pride and nationalism that have not fully surrendered to White-European western world order. Past anglo-French animosity means it is still possible to create animosity against anglo-saxon domination of Europe inside the French psyche.
Ultimately as China grows stronger and creates a strong economic relationship with France, it could create enough change in the French mindset to finally break Nato and EU.
So, China needs to give France more and more benefits.
