President Hu Jintao on Monday ordered large-scale efforts to help those affected by the earthquake that jolted Wenchuan County of south-west China's Sichuan Province on Monday. Mr. Hu directed local authorities to rescue the injured as soon as possible and to ensure the safety of people in the quake-hit areas. Premier Wen Jiabao flew into Sichuan on Monday to oversee rescue work. Mr. Wen said the Communist Party of China (CPC) and the State Council were closely monitoring the relief work. "I believe we can overcome the disaster with the public and military working together,' he said. China's earthquake administration had launched a "top-level emergency contingency plan' and would send a 180-member team to Wenchuan for disaster relief. The Chengdu Military Area Command had sent troops too, said military sources. Tian Yixiang, an officer with the emergency office of the People's Liberation Army (PLA), said the troops will assist the local government in Wenchuan to gauge the current situation and to help with disaster relief work. The tremors caused by the quake, which measured 7.8 on the Richter Scale, were felt in Beijing, Shanghai and Chongqing municipalities, Qinghai, Gansu, Shanxi, Shaanxi, Shandong, Yunnan, Hunan, Hubei, Yunnan and Jiangsu provinces, Ningxia Hui Autonomous Region, and Tibet Autonomous Region.
