Medical teams from around China have been mobilized and sent to northwestern Qinghai Province to offer aid after Wednesday's earthquake.

Northwest China's Xinjiang Uygur Autonomous Region sent 105 medical staff and 15 ambulances to the quake-hit Yushu County Thursday.

The team traveled to the quake zone, about 2,500 km from Xinjiang, by road, said Yin Yulin, director of the regional health bureau.

Another 318 medical staff and 50 ambulances from north China's Shanxi Province were sent to Qinghai Thursday by train, said a spokesman for the provincial government.

The team, carrying medicines and medical equipment, would arrive in Xining, capital of Qinghai Province, in 24 hours, said the spokesman.

Qinghai's neighoring Tibet Autonomous Region, part of which also felt the quake, has dispatched 102 medical workers to the quake-hit region as of Thursday, according to the regional government.

Altogether 21 of them have already arrived in the region and the remaining ones are the way and will arrive in Yushu Saturday.

Central China's Hubei Province has also sent a medical team consisted of 110 staff and 20 ambulances with medicines and medical equipment to Yushu Thursday afternoon, said the provincial health bureau.

They would be arriving late Friday, he said.

Another medical team with 200 staff is already well prepared to take sef-off orders, said Zhao Junchao, deputy director of the Hubei Provincial Health Bureau.

From Shaanxi Province, a team of 65 medical staff were flown to the quake-hit Yushu county Thursday.

"Ninety percent of the team members have quake-relief experience in Sichuan in May 2008," said Wu Guoqiang from the rescue team.

An 8.0-magnitude quake hit Wenchuan County in Sichuan Province on May 12, 2008 left 87,000 people dead or missing.

In Beijing, 97 medical staff set out to Qinghai by train late Thursday.

In northeast China's Liaoning Province, a 700-strong team is preparing for deployment, while a 60-strong team from southwest China's Yunnan Province has been mobilized.

"Some members are mental health experts. They are willing to help at any time," said Dong Degang, deputy director of Liaoning's health bureau.
