This area, formerly called Manchuria and now known as Dongbeiis composed of the three provinces of Jilin, Liaoning and Heilongjiang, as well as eastern Inner Mongolia. In the north, there are vast areas of coniferous forest or mixed coniferous/broad-leaved forest, a rich source of timber.
In the south there is large-scale mechanized farming on the plains and on reclaimed land. Most of China's state farms are located here. Dongbei has long cold winters and heavy rainfall during the short, hot summers.
Rapid population growth is mainly the result of heavy Han immigration from north China, beginning in the nineteenth century and accelerating after 1949. Indigenous national minorities include Manchu, Koreans, Ewenki, Oroqen, Mongols and Hui. They now constitutes less than 8% of the population.
