What was the impact of western imperialism on the "regulated societies" of china and japan?

The Western imperialism had huge effects on the ''regulated societies'' of China and Japan. It managed to change them drastically, though both countries went into two different directions.

Lot of ideas, technology, political and social views were introduced into these East Asia countries. That led to a rapid industrialization, first of Japan, later of China. Western political views were adopted too, Japan becoming a democratic country, while China was more fond of the Marxism.

Both countries developed in a Western manner. Created modern infrastructure, changed their economies, opened up to the world in pretty much every sense, though China needed some time to do that.
