China is willing to join the international community in tackling climate change, Chinese Foreign Minister Yang Jiechi reaffirmed yesterday, saying that it is "unfair and unscientific" to blame China for greenhouse gas emissions and climate change.

"If one person from developed countries could eat three slices of bread for breakfast while those from developing countries could only have one slice, who do you think should be on diet if we look at greenhouse gas emission from the perspective that all men are born equal?" he said.

"I don't think it's justifiable for some people to take the moral high ground and speak plausibly about the overall amount of China's greenhouse gas emission," Yang said.

The foreign minister noted that when the issue of climate change was being discussed, people should look at not only the aggregate but also per capita figures, not only the present but also the history, not only production but also consumption.

"As a good part of China's high quality products were exported, I hope overseas consumers realize the rising pressure China is facing for emission cuts that should have taken place in their own countries," he said. Yang said climate change should mainly be attributed to the emissions of developed countries.
