It's known that the government of China has decided to overview their attitude to demography. The PRC's authorities have decided that there must be many children in China. It's said that they'll reconsider the policy "One family - one child". Well, where will all these new legitimate children live I wonder? I think if the situation changes like this, the neighbour-countries will probably have some problems.
I guess that the problem of the Chinese demographical situation bothers us not only because their population is getting bigger, but because ours is getting small. Demographers predict that Russia's population will fall from 143 million to 100 million by 2050. In fact, I'm not against Chinese nation and can well assume that in a few decades the vast territories of sparsely inhabited Siberia will be speckled with Chinese settlements. But how will it change our culture?
Yes, they are doing it already! It is a far-going policy (50 years ahead from now). Can you imagine the geopolitical status of The Russian Federation in 2060? Awful topic to discuss? But interesting...
Neighbouring countries will have problems - Many times "YES". China has far-reaching ambitions for populating the eastern part of Russia. It has never been concealed as a geo-political fact. China needs huge new territories. Search the Internet - you will see that millions of the Chinese now are born, live, get education, work, die in RUSSIA.
