There is some agriculture in Tibetan Himalayan areas, but you are limited to mostly staples (barley is popular). The areas where animals graze in China are not densely populated, and not much of that meat is exported east to densely populated areas, at least when compared to pork (China&#x27;s most popular meat) and chicken (China&#x27;s second most popular meat); grazing animals are mostly limited to Muslim niche foods (well, not niche if you are Muslim!). Grazing animals have not had much effect on China&#x27;s population density (and if you think about it, the huge amount of land required to graze animals necessarily limits population density).<p>Jiangsu, a Chinese province of 79 million people, has twice the density of Japan, a country of 125 million. However, Jiangsu is one of those provinces that is completely flat. Much of the densities of China&#x27;s mountainous provinces (like say Hebei) are quite similar to Japan.
