The characteristics of foreign powers' invasion of China in early modern times, the differences between Russian aggression and Anglo-American law and the reasons.

The difference is that the treaties signed with Britain, the United States, France and Japan at that time plundered commerce, resources and industry by losing money, opening trading ports, establishing factories and advocating the right to build railways. The treaty signed with Russia is basically based on land cession and compensation.

Reason: Russian industry and commerce are underdeveloped, and Russia has no seaport in the Far East. Now Vladivostok, the base of the Russian Pacific Fleet, was cut off at that time.
