I disagree. Much of Northern China is drying up and water is already becoming scarce with the current population. The amount of arable land in China barely feeds the entire population even now. The reason why China was able to get ahead of the rest of the third world was because it curbed its birthrate. More people=more social/economic/political complications, regional conflicts will become even more widespread and instability will permeate from the bottom to the top. Did you know that there were 90,000 riots/civil disturbances in China in the last 4 years? That number will be much higher with 300mil more people. Without the one-child-policy, China's development will slow to a snail's pace regardless of the type of government and its institutions.
