Countries like the Maledives invest in land; that's a sensible thing to do that will save existences. What's not sensible to do is restrict fossil fuels in Europe wile China is still ramping up; it's symbolism that does not help a single person.
Every ton of carbon counts. Every Euro invested in carbon neutral alternatives makes it cheaper for poorer countries to switch. A EU wide carbon tax that is also applied to imports would perhaps also sway China into putting more effort into reducing their emissions.
There is a benefit in starting to restrict fossil fuels early. It has to be done at some point anyway because the backing resource is limited and contributes to the human-hostile terraforming of our planet. Continuing with burning coal and oil is simply a losing proposition.
Also, while defossilizing the industry base, it makes sense to enhance, increase and automate local factories to make it viable to produce things locally and not half a world away. Add a functional and effective system for recycling materials to use for new production, etc. and the long term trend is clear: China's role as the production hub of the world will diminish dramatically. From this perspective I do not understand why China does not seem to be racing like mad to restrict fossil fuels.
