Why did the Japanese general Tojo want to gain control of lane in northern China?

Japanese General Hideki Tojo sought to gain control of land in northern China primarily to expand Japan's imperial reach and secure resources. Northern China was rich in Natural Resources, such as coal and iron, which were crucial for Japan's industrial and military needs. Additionally, controlling this territory would enhance Japan's strategic position in Asia and help establish a buffer against Western powers. This expansionist policy was part of Japan's broader goal of establishing dominance in the region during the early 20th century.
