In 1276 it was founded by the Mongol rulers as Kunming County and became the provincial capital of Yunnan.
Kunming has been designated a special tourism center and as such sports a proliferation of high-rises and luxury hotels.
Kunming will be the hub and terminus for the "Pan Asia High Speed Network" using high speed trains to connect China, Cambodia, Laos, Myanmar, Thailand, Malaysia and Singapore.
It also houses some manufacturing, chiefly copper, though some other chemicals, machinery, textiles, paper and cement take key.
Kunming's streets have widened while office buildings and housing projects develop at a fast pace.Kunming long profited from its position on the caravan roads through to South-East Asia, India and Tibet.Early townships in the southern edge of Lake Dianchi (outside the contemporary city perimeter) can be dated back to 279 BC, although they have been long lost to history.The headquarters of many of Yunnan's large businesses are in Kunming.It was important during World War II as a Chinese military center, American air base, and transport terminus for the Burma Road.On the outskirts is a famed bronze temple, dating from the Ming dynasty.
