SOUTHWEST China’s Tibet has completed its water, air and soil monitoring networks and enhanced law enforcement to better protect the environment, Cering Yangzom, deputy head of the autonomous region’s environmental protection department, said.

Twenty-three automatic air quality monitoring stations have been set up in major cities and along the Qinghai-Tibet railway. It has also selected 194 monitoring sites for surface water, 84 for air quality and 110 for drinking water sources.

The plateau region is one of the areas with the best environmental quality in the world. Projects with high energy demand, pollution and emissions are banned.
