The purpose of aggression is to plunder resources and wealth, which is a long-term harm to the invaded country. Colonization is to expand territory and sphere of influence, and the fundamental purpose is plunder and possession.
It is always a painful experience for any country or nation to be invaded and colonized. However, we can't just evaluate the trauma and results of the invaded and colonized countries from a single time period in individual regions.
Extended data:
The imperialist powers occupied a large territory of China through the war of aggression, forcibly occupied China's concession, leased China Harbor, and carved up China's sphere of influence.
In order to rule China, the imperialist powers mainly take control of the China government, manipulate China's internal affairs and diplomacy, and turn those in power in China into their own agents and tame tools.
After they opened the door of China with warships and cannons, they used the privileges granted by the unequal treaties they forced the Qing government to sign with them to further expand the dumping of goods and the export of capital to China.
While the imperialist powers carried out military aggression, political control and economic plunder on China, they also carried out cultural infiltration on China. Its purpose is to propagate the idea of colonial slavery and anesthetize the spirit of the people of China.
