Yangzijiang Shipbuilding says the impact of power shortages on its operations have been "kept under control".

Many parts of China have suffered the country's worst power crunch due to a combination of surging energy demand amid the post-pandemic recovery and a reduction in coal supply under the government’s emission reduction efforts.

"A power crunch amidst shortage of coal supplies in China has led to electricity rationing and production halt at numerous factories in the months of September and October," Yangzijiang said.
