Chinese President Hu Jintao rode the Beijing metro system Wednesday to test the capital's transport preparations for the upcoming Olympic Games.

Wearing a white sleeved shirt, he stepped onto a China Railways High-speed (CRH) train that shuttles between the Beijing South Railway Station and the neighboring Tianjin Municipality.

"Beijing's metro system has developed quickly by extending its length and coverage. The system has made a great contribution to easing the traffic pressure.

"The metro's administrators should provide safe, comfortable and fast transportation for both the Olympic personnel and ordinary citizens during the Games, since visitors from home and abroad will increase a lot."

After the 20-minute ride, Hu reminded waitresses serving in the main hall of the newly-built terminal three at the airport to keep in good order and provide decent service, as the spectacular Norman Foster-designed structure was the "first gate of the country" that most foreigners saw.

Hu told some foreign passengers waiting in the terminal that China would "open its arms to welcome all the friends of the world to come."

He also inspected the main tower of the airport which handled thousands of flights daily and was delighted to know that parking bays for aircraft had been increased from 164 to 314.

"All the transportation systems prepared for the Games should do their last-minute checks and secure safety and speed as the host city promised to the world. The preparations should satisfy all visitors and benefit local residents."
