Liu made the remarks during a recent investigation and study tour to Shanxi.

The province should make more efforts in developing environment-friendly and energy-efficient technologies in coal industry, such as technologies of coal liquefaction and gasification, Liu said.

Shanxi should apply more low-carbon technologies in industrial sector, infrastructure and transport service, she said.

Liu said the province could also develop clean energy technologies such as solar and wind power generation, while promoting the development of energy-saving and new energy vehicles.

Through the smooth application of low-carbon technologies, the province should transform its economic development into a pattern of high energy efficiency and low carbon emission, she said.
