Reuters reports that analysts at Nomura cut their forecast for China's annual GDP growth in 2021 to 7.7% from 8.2%, citing the impact of factories pausing operations amid power outages and environmental policies.

"Over recent weeks, a surging number of factories across China have been forced to cease operations," due to higher coal prices hitting power supplies and government mandates to meet carbon emission reduction targets, they said in a note.

This downward pressure on growth comes on top of curbs on the property sector, they added.
