Europe and India are the regions that are actually surprisingly negligible. Africa and the rest of the developing world doesn't make a blip.
When you import goods, you import their emissions. It's just super hard to measure (and we like to blame it all on China).
China just had an astronomically high population. They will always be higher overall due to this.
An actual measurement of this needs to be performed capita.
Similar, countries with aging population will see an increase in emissions per capita regardless if they are actually decreasing emissions, as long the population loss is greater than emissions decreases.
And China is already leading the world in moving to renewable technology, they are moving in the right direction (not entirely for altruistic reasons - it fulfils their ambitions of energy self-sufficiency).
