Qingdao-based firm recalled cars from Singapore, says it found no risk to safety

Qingdao-based CRRC Sifang Co Ltd, a subsidiary of the country's largest trainmaker China Railway Rolling Stock Corp, said on Wednesday that it had recalled defective metro trains used in Singapore, and the first batch of repaired trains have been back in service running nearly 300,000 kilometers.

The company's comments came after foreign media reported that several metro trains, jointly designed and manufactured by Japan's Kawasaki Heavy Industries Ltd and CRRC Sifang, are being shipped back from Singapore to their manufacturer due to issues including cracks in structural components and an insufficient battery system.
