Europe views itself as the world leader and wants to limit climate change to 2 C above pre-industrial levels by 2050. It has pledged to cut carbon emissions by 20 percent by 2020, and to raise this to 30 percent if there is agreement at Copenhagen.

In the past few years while adhering to the Scientific Outlook on Development Hu promotes, China has been working towards rigorous targets - which it had set for itself - to promote clean energy, push for energy efficiency and cut greenhouse emissions.

I hope China will categorically outline her stance on vital international issues. I would be totally disappointed if deliberations after this UN summits turn out to be "the same old wine in old cups."
