No . . .
China is not a tropical rain forest.
Africa has a large grassland surrounding the rift vallies.
The Amazon basin is a large producer, but even at the height of the rainy season (very un-natural there), but it has also been greatly industrialized over the past 2 decades with gold hunters and new processing boom-towns springing up like weeds (shave and a hair cut, $200.00 US). And the northern Argentina pampas are prone to natural fires as a part of the grass' growth cycle.
