BEIJING, Aug. 14 (Xinhua) -- China released the Eleventh Five-Year Plan (2006-2010) for disaster relief Tuesday, promising to improve its natural disaster response system to cope with the "more frequent" natural calamities triggered by global warming.

"It must be guaranteed that all people who are affected by disasters have access to enough food, drinking water, clothes, temporary accommodations and medical aid within 24 hours," it said.

The government document said that "a variety of natural disasters are affecting 300 million people, torn down three million houses, caused 20 million yuan of direct economic losses every year to China over past 15 years."

"With the more prominent trend of global warming, the frequency and intensity of natural disasters will both increase," said a senior official with the National Disaster Reduction Commission when explaining the document to Xinhua.

"Natural disasters have turned to be an important factor restraining China's economic and social development," he said.

The country will establish a unified information platform to share the natural disaster-related information, and national natural disaster surveillance, early-warning, emergency response systems will be established and improved from 2006 to 2010, according to the Plan.

The Plan also set a national for economic loss control. "The direct economic losses caused by natural disasters should be controlled at less than 1.5 percent of the country's annual GDP from 2006 to 2010," it said.

The government document said that global warming may cause more frequent typhoons, floods, rock-mud flows, droughts, heat waves in China. Desertification, forest fire, plant disease and red tide would be more prone to occur.

It admitted that China's more than 70 cities and more than 50 population are distributed at the areas susceptible to natural disasters.
