Helicopter hovering overhead, thousands of cheering fans, music blaring from loudspeakers...one would be forgiven for thinking famous rockstars were coming to the Pairi Daiza zoo, 60km southwest of Brussels, on Sunday. But then again, few rockstars would be received personally at the airport by the country's prime minister, deputy prime minister, defense minister and then be given a police escort to their final destination. Such were the courtesies extended by Belgian authorities to Hao Hao and Xing Hui -- the first giant pandas China has sent overseas for a lease term of 15 years instead of the usual ten.
