Vicente Gonzales Loscertales, secretary-general of the International Exhibition Bureau (BIE), said that the flags of the official participants represent the commitment of the international community to take part in the global dialogue that Shanghai Expo is fostering.

"These flags remind us that we have come together as a global community under one goal to pursue cultural, economic and social innovation for 'Better City, Better Life'," he said.

"I am really looking forward to the Expo. I have got tickets from my neighborhood committee," he said. "I want to take my mother to visit the China Pavilion in next few days."
