The strategic intention and main steps of Japan's invasion of China in modern times

Japan's lack of domestic resources has limited its national development. He launched a war for the national interest, sent troops to the three northeastern provinces under the instructions of Emperor Hirohito, and occupied the Northeast through the September 18th Incident. After the Lugouqiao Incident, there was a confrontation with the China army. Later, the so-called "Manchukuo" was established with "autonomy of five northern provinces" and occupied half of China.
