The Sichuan leg of the Beijing Olympic torch relay has been cut by a day and postponed to the week before the Games' opening ceremony to allow for relief work in the quake-torn province.

The relay resumed yesterday in the coastal city of Ningbo after three days of national mourning for the victims of the Sichuan earthquake which killed more than 50,000 and left millions homeless.

The Sichuan leg, originally scheduled for June 15-18, had been pushed back to Aug. 3-5, the Beijing Organising Committee for the Olympic Games (BOCOG) said on its website.

"The relay leg will be closely tied to the earthquake disaster and relief work and will emphasise the theme of 'Torch relay, love and care'," BOCOG said.

The torch relay was scheduled to travel through quake-affected areas, including Mianyang and the Sichuan capital, Chengdu. Other cities included Yibin, Zigong, Guanghan and Guang'an, the home town of Deng Xiaoping, the late paramount leader and revered economic reformer.

Organisers did not say whether the route would be affected, but said it would be the penultimate stop before the torch's arrival in Beijing.

The Games opening ceremony is on August 8.

The relay schedule in other provinces and cities would be adjusted to allow for the change, BOCOG said, without providing details.

History's longest torch relay has been dogged by controversy, with anti-Chinese protests blighting several legs and weather delaying the ascent of Mount Everest.

After the 7.9 magnitude quake struck the southwestern province, relay organisers originally decided to proceed as planned after a minute's silence at the beginning of each day. But on Sunday, they suspended the relay for three days from Monday to Wednesday.
