When the Japanese invaded China, did North Korea send troops to support China? When I was watching TV, the host said that Japan attacked us and North Korea sent troops to support us.

Before the full-scale invasion of China, Japan had occupied the whole Korea/North Korea, and there was no question of sending troops to support it. However, during the War of Resistance against Japanese Aggression period, North Korean officers and men under the Northeast Anti-Union were organized, with Jin Guangzhu as the leader and later renamed Kim Il Sung. He fought side by side with China soldiers and returned home after the victory of the Anti-Japanese War.
