Some 2,000 delegates from governments and NGOs of 163 countries are attending the Bangkok talks, which opened on Monday, kicking off a fresh round of international negotiations after Parties to the UNFCCC agreed after difficult bargaining last December in Bali, Indonesia, on a road map for strengthening international action on climate change.

The new complex agreement, expected to be reached in Copenhagen Climate Change Conference in late 2009 in Denmark, will have one of its focus on defining further technical and financing support and assistance by the developed countries for developing countries in climate change mitigation and adaptation.

A number of different options for resourcing fund for global cooperative efforts are being discussed, said de Boer. Among them, China has suggested that the developed countries devote 0.5 percent of their GDP a year to help developing nations combat climate change, while Germany proposed auctioning a portion of emission rights and using the proceeds for international cooperation on climate change mitigation and adaptation.
