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.
Where did you get the figures of the white-west having a combined GDP of 60 Trillion in nominal terms and having a combined global GDP share of 55%
Per latest GDP of EU last year was $16 Trillion and the U.S. was at $25 Trillion, combined them together that's $41 Trillion. Canada's GDP was at $1,988,366 in 2022 and Australia's GDP was $1,635,255M U.S.D. New Zealand was $246,974M USD. Unless am missing anymore white European countries on this list the combined amount doesn't reach $60 Trillion. I used countryeconomy.com for reference.
As for your yet another egregious calculation regarding your assertion that U.S. and EU/white countries combined share of GDP of 55% is just flat out wrong.
As of 2021, both together (U.S. and EU) share 42.4% and 30.7% of the entire GLOBAL GDP in nominal and PPP terms respectively. As per projections by IMF in 2021. Source: StatisticsTimes.com comparing United States and European Union by Economy.
