China intensified airport security checks for flights to the United States following the thwarted Christmas day terror attack on a U.S. passenger flight, said Foreign Ministry Spokeswoman Jiang Yu on December 29, 2009.

The move was in accord with international conventions and the requirements of the U.S. Government, she told a regular press conference.

She said China had always maintained tight airport security to ensure the safety of travelers. "China is opposed to terrorism in any form, and this stance is consistent and clear," she said.
