The Chinese leader said a significant share of China's total emissions fall in the category of subsistence emissions necessary to meet people's basic needs.

"Third, as a result of changes in international division of labor and manufacturing relocation, China faces mounting pressure of international transferred emissions," he said.

He said the Chinese government, with a responsible attitude toward the Chinese people and people of the whole world, takes climate change very seriously.

"We have made it a strategic task to build a conservation culture and we adhere to the basic state policy of conserving resources and protecting the environment," Hu said.

China is making efforts to ensure that its industrial structure, growth model and consumption pattern are energy and resource efficient and environmentally-friendly, he said.

"We have, in line with our economic and social development plans and sustainable development strategy, formulated China's National Climate Change Program, set up the National Leading Group to Address Climate Change, promulgated a series of laws and regulations and adopted a host of measures to tackle climate change," said the Chinese president.

China, which started efforts by saving energy and cutting emissions, has taken a series of measures, including conserving energy, improving the energy mix, raising energy efficiency and promoting afforestation, and has achieved noticeable results, he said.

"We have set the clear targets that the year-end energy intensity per unit of GDP of 2005 will be reduced by 20 percent by2010, total discharge of major pollutants will be cut by 10 percent and forest coverage will increase to 20 percent from the 2005 figure of 18.2 percent," Hu said, adding that China is firmly committed to meeting these targets.
