Tianjin, the world's 10th-busiest port, will relocate chemical plants from the Tianjin Binhai New Area where the blasts occurred to the Nangang Industrial Zone, 25 km (15.5 miles) away, according to the official China Daily, citing Tianjin Mayor Huang Xingguo.
The Communist party's anti-graft watchdog promised to crack down both on corruption and on those responsible for violating laws and regulations which had led to the explosions, but stressed the importance of maintaining political stability, according to a statement on the Central Commission for Discipline Inspection website on Thursday.
Chinese state media on Wednesday pointed fingers at executives of Ruihai, the company which owns the chemical warehouses, over the disaster, saying they used connections to obtain fire safety and environmental approvals.
The Tianjin government announced on Wednesday that after days of investigations, they had determined the warehouses contained 2,500 tonnes of 40 types of dangerous goods, classified into three categories, according to the official Xinhua news agency.
There were 1,300 tonnes of potentially explosive oxidising chemicals, including ammonium nitrate and potassium nitrate, 500 tonnes of flammables, including sodium and magnesium, and 700 tonnes of deadly poisons, mainly sodium cyanide.
