BMW Group said production at all its plants in the northeastern Chinese city of Shenyang resumed on Thursday.
The German automaker had suspended output in Shenyang since March 24 because of COVID-19 control measures.
BMW and its Chinese joint venture partner, Brilliance China Automotive, operate a Shenyang manufacturing base that includes two vehicle assembly plants, a research and development center and a powertrain plant.
State-owned Chinese automaker FAW Group has restarted some production at its Hongqi plant in Jilin, the official Xinhua News Agency reported on Thursday, as the northeastern province emerges from a COVID-19 lockdown.
FAW's joint ventures with Toyota and Volkswagen will also gradually resume operations at local plants, Xinhua said.
