Shanghai's two airports add security

Passengers advised to arrive a half-hour earlier at Pudong and Hongqiao terminals

Security checks have now begun at the entrances of Shanghai's two international airports as part of the implementation of a national anti-terrorism law.

As of Monday, all people and their belongings must clear checks at the entrances of Shanghai Pudong International Airport and Shanghai Hongqiao International Airport - as well as pre-departure checks, an airport official said.
