Chinese people must now register their names when delivering parcels after authorities tightened safety inspections following multiple mail bombs.
The move is part of a five-month long campaign launched by the central comprehensive management office, along with 14 government departments including the Ministry of Public Security and the State Administration of Work Safety, to reinforce safety management of delivery services nationwide, according to a central statement issued Thursday.
The delivery service staff must also check the goods before packaging, and all envelopes and parcels must go through a X-ray machine.
The 15 organs will also beef up supervision over production ,transportation, sales, storage and usage of explosives and dangerous goods, and severely crack down on related crimes, said the statement.
On Sept. 30 and Oct. 1, several explosions were caused by letter bombs at different places in Liucheng County, south China's Guangxi Zhuang Autonomous Region, killing at least seven people and injuring dozens.
Police arrested a 33-year-old suspect surnamed Wei, who was found to have hired others to help deliver the letter bombs.
On Aug. 12, two blasts ripped through a warehouse in north China's Tianjin Port, where large amounts of toxic chemicals were stored, including around 700 tonnes of sodium cyanide. Death toll from the blasts exceed 160.
