(WU WEI)

Su Wei, China's chief climate negotiator at the UN climate talks, has become a household name for his high-profile defense of the interests of China and the developing world as a whole at the 2009 UN Climate Change Conference in Copenhagen, Denmark.

Many of his quotes, in particular, are among the hottest hits on the Internet. For instance, when criticizing developed countries of failing to offer enough aid to developing countries in the fight against climate change, he said that a mooted $10 billion in yearly financial help from rich nations would not "cover a coffee in the rich world or a coffin in poor countries at the sharp end of changes in climate," as they were only at a level of less than $2 per person if divided by the world population.

Su is director general of the Department of Climate Change of the National Development and Reform Commission. He began to participate in UN climate talks in 1989.
