History
Golmud is a rather young city. It was first established in 1954 when the Transportation regiments of Qinghai-Tibet Corps set up a food distribution base, staffed by 10 people, at the current location, and in May of that year, construction on the Qinghai-Tibet Highway commenced. Scientific exploration of the mineral resources of Qarhan were undertaken in the 1950s, leading to the discovery of the area's potash and gas fields. Systematic surveying was undertaken in the 1960s and 1970s, with the railway permitting industrial exploitation from the 1980s. The first oil pipeline and potassium fertilizer factory were opened in 1989. The Golmud Kunlun Economic Development Zone was opened in 1992. In 2004, a second pipeline arrived. In the 2010s, an influx of further investment followed realization of the importance of the Sanhu's supplies of lithium and rare earths for modern personal electronics and electric cars. In 2016, over 85% of goods movement with Tibet passed through Golmud.
