Japan and China wanted to isolate themselves from the world in order to preserve their traditional cultures.
Explanation:
During the early nineteenth century, both Japan and China established an ultra-nationalist sentiment and a certain repudiation of all that was Western. The Chinese government and the Japanese government viewed their cultures as superior and should not be mixed with Western culture.
In order to prevent the traditional culture of these countries from having contact with the cultures they found inferior, Japan and China decided to close their borders to the west and isolate themselves from the world.
The answer is that foreign stuff
or goods were treated inferior to those produced in China. They believe the teaching of Confucius that
merchants harm society by shamelessly seeking or getting the profit at the
expense of others, merchants are inferior in nature and should be despised.
