How did european imperialism in africa differ from that in china?

Economic imperialism in China led to war and political collapse, while formal colonialism in Africa led to oppression of native peoples.
The isolation of China led to them falling behind the industrialized war. They then became engaged in numerous wars,including the three opium wars, as well as the Sino-Japanese war. As they were also behind in military technology and modern warfare, they were defeated and were forced to give concessions to theimperialists. Unequal treaties forced them to open ports, and grantterritorial concessions. China's land was exploited for its natura lresources, and the Europeans gained the right to build a railwaytransportation system within China.

Americans agreed to the settlement terms established by the mexican government.
