He is really worried about Chinese population in every thread...The biggest threat related to him should be the low-quality population which poses a huge threat to society back in his own country...
India's fertility rate has actually come down significantly, and the population is beginning to stabilize. Also, the increase in productivity can had very easily, especially when you have <7k per capita dollars economy.
But, in real size it is absolute size that matters. Also, what will happen of the aged, who will support them. Population is always an asset, especially as a market. And technology is the answer to sustain a high population efficiently.

The single biggest problem with population is that it is treachrous.
What does that mean?
Population has its own inertia.
Let us say 2 people start at time 0th generation.
They give birth to 6children, who are at 1st generation. So total population = 2 + 6.
Next, 6 children give birth to say 30 children. Tot population = 2 + 6 + 30. By 2nd generation.
Next, 30 give birth to 70 children. tot population = 2 + 6 + 30 + 70. By 3rd generation.
Next 70 children give birth to 100tot population = 6 + 30 + 70 + 100By 4th generation. (
Note that the 0th generation is dead)
Next 100 give birth to 100. Tot Population = 30 + 70 + 100 + 100. By 5th Generation (
Note that the fertility rate has already come down to 2, and since we are not taking here any premature deaths, this is the replacement ratio, yet the population will continue to increase for a while.)
Next 100 give birth to 90 Tot Population = 70 + 100 + 100 + 90. (
Note: Fertility rate is below replacement, but due to past inertia the net population is increasing.)
Next 90 give birth to 80. Tot Population = 100 + 100 + 90 + 80 (
Note: This is a very painful age, because just see the increase in size of the aged.)
Next 80 give birth to 60. Tot Population = 100+ 90 + 80 + 60 (
Note: This is actually the first year that population declines, taking 3 extra generation before fertility rates started reflecting in population growth trends.)
Next 60 give birth to 30. Tot Population = 90 + 80 + 60 + 30. (
The population has already halved.)
Did you notice something? That it took only 1 generation from the decline in population to being reduced to half!)
Demographics is a really complicated thing, and it is both slow and fast. It carries a lot of inertia, and can't be controlled easily.
