SHANGHAI (Reuters) - Twenty-one people were killed and seven injured when a vehicle carrying railway construction workers overturned in northwest China's Gansu Province on Saturday, the official Xinhua news agency said.
China has invested heavily on railway infrastructure to connect the vast country during years of strong economic growth.
But authorities recently suspended new rail projects after a collision between two high-speed trains in July killed 40 people and fanned public anger over transport safety issues.
Shanghai authorities also came under fire in September after the worst subway accident in 42 years raised fresh concerns that the world's second-largest economy was sacrificing safety in the rush to develop.
Xinhua said the vehicle overturned in Manwa township in Lintao County. It was not immediately known how many were in the vehicle, which was heading to a railway construction site.
It was also not clear if all those killed and injured were construction workers.
Local authorities are investigating the cause of the accident, Xinhua said.
