Tibetless China is still a lot bigger than India and doesn't have that 94% property. The spirit of the GP's comment holds, I think.

China:

  ~94% of 1.357b = 1.28 billion population. 
  ~40% of 3.7 mill = 1.5 million square miles.
  = ~0.85 billion people per million square miles.

India

  1.252 billion people on
  1.269 million mi
  =~ 1 billion people per million square miles.

So, India is around 15% denser. Of course you can avoid the strait line cut and push China's density much higher, but the point is they are not that far off where people actually live.

Where are you getting the 40% figure from? Are you saying that Tibet(-ish) is 60% of the land area of China?
