Kunming, the capital city of Yunnan Province, serves as the center of the province in terms of politics, economics and culture.

As long as 2,000 years ago, Kunming served as a major textile distribution center on the "Southern Silk Road." This section of the road started from Sichuan, traversed through Yunnan and continued on into Vietnam. In the 14th century the Ming Dynasty took over Yunnanfu, as Kunming was then known, building a walled town on the present site. In the 19th century, the city suffered several sieges at the hands of the sultan of Dali. Kunming came under western influence during the middle of the 19th century when France took control of Indochina, and Britain took control of Burma, accessing the city from the south. By 1900 Kunming had opened for foreign trade. The French sought to capitalize on the region's copper, tin and lumber resources and in 1910 their Indochina Railroad reached the city and is still in operation today. Kunming expanded during WWII, when factories were established and refugees from eastern China, fleeing the Japanese, poured into the city. Anglo-American forces sent supplies to Nationalist troops entrenched in Sichuan and Yunnan to help their efforts against the Japanese. Supplies came overland on the famous Burma Road, a 1000-km haul from Lashio to Kunming's Renmin Road, a road carved out of the mountains in 1937-38 by 160,000 Chinese with virtually no modern equipment.
