Rescuers pulled a four-year-old girl and a 68-year-old woman from a collapsed house on Monday, five days after an earthquake left more than 2,000 people dead.

The two survivors had been trapped under a bed in their mud hut in a village about 20 kilometres from the badly hit town of Jiegu, China Central Television reported.

Food and water had been passed to the pair through gaps in the rubble of their house, CCTV said.

The woman was said to be in critical condition after she was rescued, while the child had heart problems from the trauma.

Even as rescuers pulled the pair out of the rubble, the death toll from the 6.9-magnitude quake last Wednesday in a remote Tibetan region of western China rose to 2,039 with about 200 still missing, the official Xinhua News Agency said. In addition, more than 12,000 were injured.

Aid poured into the area as supply convoys clogged the road into Jiegu, about 1,000 kilometres from the provincial capital of Xining.

Bottled water was stacked at a depot on the edge of Jiegu, while mobile toilets were also brought in amid rising concern over the spread of disease.

Relief efforts could be hindered by snow which began falling Tuesday on the high-altitude region. Snow and sleet are forecast for the next three days, with temperatures dropping by nearly 10 C to far below freezing, according to the weather bureau, Xinhua reported.

President Hu Jintao visited the area on Sunday, pledging the Chinese government was doing all it could to help.

However, with some rescue teams leaving on Monday, the situation appeared to be shifting to rebuilding and recovery of remaining bodies.

In Jiegu, hundreds Buddhist monks in crimson robes performed funeral prayers, picked at rubble with shovels and threw food from trucks to survivors.
