Northwestern China
Northwestern China is a region in the People's Republic of China. It consists of five provincial administrative regions, namely Shaanxi, Gansu, Qinghai, Ningxia, and Xinjiang.
The region is characterized by a arid continental climate. It has a diverse population including significant ethnic minorities such as Hui, Uyghurs and Tibetans. Culturally, the region has historically been influenced by the Silk Road.
Historic security considerations
Chinese dynasties from the Qin to the Qing period placed high priority on maintaining stability and security in the region, motivated by concerns about potential threats from the Northwest.Security concerns have continued under modern governments. During the Republic of China period, the government was only able to exercise loose control in the Northwest. In 1933, Pan-Islamic and Pan-Turkic separatists declared an Islamic Republic of East Turkestan based on constitutionally-enshrined Sharia law. The short-lived separatist Islamic Republic was not recognized by any other countries and was suppressed after three months of existence.
With Soviet Union backing, separatists declared a second short-lived East Turkestan Republic in 1944 based in Yining. The Soviet Union withdrew its support in June 1946. A separatist movement drawing on the legacy of the short-lived East Turkestan Republics continues today.
