Shuanghu County is located in Nagqu Prefecture and was previously administered by Nyima County, state-run Xinhua news agency reported.
Shuanghu is named after the two lakes of Kamru and Racho in its jurisdiction, it said.
Although the county's Purog Kangri Glacier, the third largest in the world, has drawn tourists to the area, the local economy is lackluster due to poor living conditions and transport infrastructure, said Namphel, head of the county committee of the Communist Party of China.
