Shanghai's two airports have ramped up security checks as part of an anti-terrorism drive that was launched on Monday.
All passengers and their belongings must now clear anti-terrorism security before entering Shanghai Pudong International Airport or Shanghai Hongqiao International Airport, according to an airport official.
The newly launched checks will focus on passengers' carry-on baggage, looking for restricted items such as knives, flammable materials, explosives and guns.
An additional 27 check points have been added in Pudong and 14 in Hongqiao, on top of the existing security check area.
The heightened security measures are being implemented as part of the nation's first anti-terrorism law, which came into effect on Jan 1.
According to article 34 of the law, security checks should be carried at all airports, railway stations, ports, metro stations, long-distance bus stations, and other high-activity areas, according to Xia Gongwei, an official from Pudong International Airport.
