How long is the border of China?

China's land border is more than 20,000 kilometers long. The coastline of Chinese mainland starts from the mouth of Yalu River between China and North Korea in the north and reaches the mouth of Beilun River between China and Vietnam in the south, with a total length of18,000 kilometers.

The border of China refers to the border of China. Historically, most of China and its neighboring countries have no borders. Emperors in ancient China respected the traditional concept of "the best in the world", and there was no boundary problem between China and neighboring countries in the modern sense.

With the introduction of the concept of sovereignty in western countries and the invasion of western colonists, the problem of sovereignty boundary became increasingly prominent, and the king of Qing Dynasty began to realize that he wanted to protect the border and defend the country. Under the aggression of western colonialists, China was forced to sign an unequal treaty and cede a large territory.

Extended data:

China is the country with the longest land border and the largest number of neighboring countries in the world, and it is also one of the countries with the most complicated border situation. The total length of its land border is more than 22,000 kilometers, and it borders North Korea, Russia, Mongolia, Kazakhstan, Kyrgyzstan, Tajikistan, Afghanistan, Pakistan, India, Nepal, Bhutan, Myanmar, Laos and Vietnam in an anticlockwise direction.

It is of epoch-making significance for China to solve the land boundary problem with its neighbors. This is not only the first time in China's history to draw a clear line with its neighbors, avoiding border conflicts and wars, and opening a new chapter in security cooperation, but also providing an important platform for China to carry out economic and trade cooperation and cultural exchanges with its neighbors, turning the source of conflict into the source of cooperation, which is of great historical significance to the security and cooperation of Asia as a whole.
