Beijing: A blast near a chemical plant in China’s northern Hebei province early Wednesday killed 22 people and injured at least 22 others, the local government said.
Authorities are investigating the cause of the blast in Zhangjiakou city, the local government said in an online statement.
In August 2015, 165 people were killed after a chemical warehouse explosion in the port city of Tianjin. A government report found that the disaster was cause by improperly or illegally stored hazardous materials.
China has vowed to improve industrial standards, but environmentalists say they fear oversight weaknesses persist, including an opaque production process for hazardous chemicals.
