     BEIJING-Alarmed by the overreaching ambitions of many Chinese provinces to grow at all costs, China's

top economic chief is calling on officials to calm down and spare a thought for the environment.

     Zhang Ping, who heads China's National Development and Reform Commission, the central economic

planning agency, said only five or six of China's 30 provinces are targeting annual economic growth of 8 or

9 percent.

     The remaining provinces are aiming for growth rates of more than 10 percent this year, with some wanting

to double economic output in the coming five years.

     "China has a planned energy supply of about 4 billion cubic tons of coal equivalent (等量的) for the next

five years, and this is not enough to meet demands for economic growth to double," he was quoted as saying

on the news portal sina.com.

     Beijing is increasingly concerned with the ambitions of Chinese provinces across the country to chase high

growth despite the central government's urgent request for a more moderate and sustainable (可持续的) pace

of expansion.

     Years of rapid economic growth have taken a toll on China's environment, with Beijing trying to remove

some of the damage now. It has an annual growth target of 7 percent for the next five years, well down from

last year's 10 percent.

     Zhang said Beijing has asked local governments to take into account the supply of "energy, environment,

water and land" to set more reasonable growth targets.
