The huge scale of investments required to do Net Zero CO2 Emissions would raise China’s GDP by as much as 5% later this decade, with a modest ongoing positive impact due to reduced fossil-fuel imports.
China’s investments would not only drive dramatic reductions in its own CO2 emissions, but would also lower the cost of clean energy, creating a positive “spillover” effect in other countries.
This is co2 neutral ie no emissions or offset emissions, China is still on track to reach co2 Paris agreement targets ahead of schedule:

The first ten years of the agreement, they were allowed to increase emissions, as part of the historical understanding that the West traditionally had been the problem.
