Organisers of the 2012 London Olympics say they will not aim to beat the scale of the Beijing Games but will instead focus on providing a lasting legacy for the surrounding community.

The chairman of the 2012 organising committee Sebastian Coe said his team would focus on providing sustainable venues and not just 16 days of spectacular sport.

"The International Olympic Committee themselves recognise that this is the last edition of a Games which is going to look and feel like this," Coe, a double Olympic champion, said.

"It's a mistake to think that Games model themselves on previous Games. Every Games I've been to has been very different.

"But we can be creative - we know that more people will probably come to London for the Games than to other cities."

Advertising its new economic clout, China has invested $43 billion on its Games and the opening ceremony in the 91,000 seater-Bird's Nest stadium was a spectacular affair played out to 80 world leaders.

The London Olympic stadium will hold 80,000 people during the Games but will be scaled back afterwards to a more compact 25,000-seater.
