Shanghai World Expo throws open doors

Hundreds of thousands of people flooded into Shanghai's World Expo yesterday at the start of a six-month showcase of culture and technology seen as the latest sign of China's growing economic might.

Organisers have said all 500,000 tickets are sold out for opening day at the massive Expo park along the Huangpu river, where visitors will wander through the exhibits of 189 nations, as well as dozens of companies and organisations.

"Everything is very colourful," Cui Yan, a 23-year-old Chinese university student, said outside the Mexican pavilion. "The architecture is amazing."

"There are so many highlights - I'm worried I can't see all of them on this trip," said Cui, who travelled from Ningbo, in neighbouring Zhejiang province, to be one of the first to catch a glimpse of the Expo pavilions.

A sea of people waited to visit China's red inverted pyramid - the centrepiece of Expo park - with 50,000 tickets handed out within five minutes of the park opening.

Queues were long at all pavilions but by 4.30 p.m. about 200,000 people had entered the park - less than half the number of tickets sold.

Eager visitors used umbrellas to shield themselves from the blistering sun as they waited patiently, the long queues doing nothing to dampen their enthusiasm.

"I want to see the Canada pavilion first. So many of my relatives have emigrated to Canada and I want to get an idea of what kind of life they're living," retiree Huang Huifang, 58, said as she ran towards the building.

Shanghai kicked off the Expo on Friday night with a star-studded music and fireworks extravaganza, signalling it would be bigger and brighter than the more low-key world's fairs in recent years.

Italian tenor Andrea Bocelli, Hong Kong action film star Jackie Chan and Chinese pianist Lang Lang performed for thousands of guests, including Chinese President Hu Jintao and about 20 other world leaders.

A record number of countries are participating in the event, which is expected to attract at least 70 million visitors - the vast majority of them Chinese, many of whom have never travelled outside the country.
