With Terminal 3, the Beijing capital airport can handle up to 76 million passengers annually, more than double the previous capacity. The airport was expected to receive about 5.56 million people during the Games.

Three subway lines and a 28-kilometer light rail linking the downtown with the airport went into operation before the Games, extending the city's total length of track to 200 kilometers. At the same time, Beijing keeps the prices of public transport low.

Meanwhile, 34 special bus routes linking Games venues are operating during the event and they are free to those who have Olympic tickets.

Since the March 14 Lhasa riot, safety has been a major concern for the Games, but Beijing has 150,000 security guards plus 290,000 volunteers doing patrols.

Beijing also deploys security staff at hundreds of checkpoints on road entries to the city. The subway also carried out security checks.

As foreign media put nearly everything Chinese under the microscope during the 17 days, the government fulfilled its Olympic bid commitments and promised that reporters would be able to report the Games freely.

Addressing the closing ceremony of the Beijing Olympics, Liu said, "The Chinese people, teeming with enthusiasm, have honored the commitments they solemnly made."
