Central Asia is the abbreviation of Central Asia, which refers to the inland areas of Central Asia. This concept was first put forward by German alexander von humboldt in 1843, and its scope has many definitions. In a narrow sense, it is generally limited to "five Central Asian countries". "Five Central Asian countries" refer to Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan.
Geographically, Central Asia is located at the junction of Asia and Europe, in the middle of Russian, China, Indian, Iranian, Pakistani and other big countries or regional powers. It is a transportation hub that runs through Asia and Europe. It has always been the only place that passes through the east, west, north and south, and the ancient Silk Road passes through here. After the end of the Cold War, Central Asia became an important strategic buffer zone.
