PEOPLE must now register their names when delivering parcels after authorities tightened safety inspections following multiple mail bombs.

    The delivery service staff must also check the goods before packaging, and all envelopes and parcels must go through an X-ray machine, according to a statement issued Thursday by the national committee for comprehensive treatment of social management.

    The new policy kicks off a five-month-long campaign jointly launched by 15 organs of the Central Government, including the Ministry of Public Security, which will last until next March targeting mail bombs and dangerous substances, said the statement.

    Multiple explosions in the Guangxi Zhuang Autonomous Region killed at least seven people and injured 51 others in Dapu Township, the seat of Liucheng County, on Sept. 30 and Oct. 1.

    Police arrested a 33-year-old suspect surnamed Wei, who was found to have hired street vendors to deliver express mail packages containing explosives across the town. The devices exploded when the parcels were opened.

    In the latest case, Beijing’s quarantine authorities found two separate parcels containing HIV-antigens, which could lead to HIV infection, at Beijing Capital International Airport on Wednesday.

    In China, only 3 percent of regular air delivery packages are randomly checked by quarantine officers, according to the authorities.

    In 2014, Chinese people had 14 billion parcels delivered, according to the State Post Bureau.
