What is the geographical environment of China?

The basic situation of geological environment in China is as follows:

1. The geographical environment of China is land on three sides and sea on the east.

2. China is surrounded by land on three sides, with wasteland and frozen soil in the north, Gobi and desert in the west and mountains, rivers and tropical rain forests in the south, which is a relatively closed environment in history. Now, with the development of land and sea transportation, the eastern and western parts have become the strategic locations of China's economy and energy, and are at the forefront of foreign exchanges.

3. China is one of the countries with the largest number of land and sea neighbors in the world, with powerful land and sea neighbors, such as Japan, Russia, India and South Korea.

4. China has complicated territorial and territorial disputes with quite a few neighboring countries. For example, the dispute between the East China Sea and the South China Sea.

5. There are many cross-border ethnic groups around China and neighboring countries, and a series of hot issues and potential unstable factors are distributed around China.

Geo-environment, also known as geopolitics, is a national defense security issue put forward by Ratze in 1897 F. To understand China's national defense security issue, it is necessary to clarify where China's security interests are manifested from the aspects of China's overall security needs, the strategic interests of realistic or potential opponents and its China policy, China's geographical environment and the strength comparison with future invaders, and correctly analyze what requirements these security interests put forward for China's national defense security strategy.
