Why did Japan develop heavy industry in Liaoning during its occupation?

During the period of Japanese occupation (1932–1945), Japan developed heavy industry in Liaoning primarily to transform the region into an industrial and military base to support its broader expansionist goals across Asia. Japanese policy was specifically designed to develop the province's resources in a manner that would complement the economic strength of Japan.12

This industrialization was facilitated by the region's abundant natural resources, particularly its rich deposits of iron ore and coal, which provided the necessary raw materials for heavy manufacturing. By the end of World War II, these investments had made the region the most industrialized area in China. While this focus on heavy industry at the expense of agriculture and light industry has been criticized, the resulting infrastructure proved to be of significant importance to China's own industrial development after 1949.312
