A fire at a chemical storage facility in China's eastern Jiangsu province is under control and no casualties have been reported, the local government said on its official Twitter-style Weibo account on Friday.

State media reported earlier that the chemical storage facility in Jingjiang city, part of Jiangsu province, caught fire after an explosion at about 9 a.m.

Photographs on the news agency's website showed a thick plume of black smoke rising into the sky.

China has vowed to improve industrial safety standards after chemical blasts in the Chinese port city of Tianjin last August killed 165 people.
