Xishuangbanna Dai Autonomous Prefecture

Xishuangbanna, sometimes shortened to Banna, is one of the eight autonomous prefectures of Yunnan Province. This autonomous prefecture for Dai people lies in the extreme south of Yunnan province, China, bordering both Myanmar and Laos. Xishuangbanna lies at latitude 21°10′-22°40′ and longitude 99°55′-101°50′ east, on the northern edge of the tropics south of the Tropic of Cancer. It has an area of 19,124.5 square kilometers, bordering Pu'er City to the northeast and northwest, Laos to the southeast and Myanmar to the southwest. The border is 966.3 kilometres or 600.4 miles long, one river connects six countries, and there are four national ports. The prefectural seat is Jinghong, the largest settlement in the area and one that straddles the Mekong, called the "Lancang River" in Chinese.

This region of China is noted for the distinct culture of its ethnic groups, which is very different from that of the Han Chinese. The people, architecture, language and culture more closely resemble those of the Shan, Dai and Tai peoples, which includes the Thai and Lao. By the end of 2024, the resident population of the whole state will be 1,336,000.
