Chinese Premier Wen Jiabao spoke to Prime Minister Dr Manmohan Singh to discuss climate change issue amidst rift in Copenhagen Summit on the leaked Danish proposal. Chinese Premier also spoke to Brazil’s President Luiz Inacio Lula da Silva to cooperate on climate change.<br/><br/>AIR correspondent reports the phone calls came a day after the tiny Pacific island nation of Tuvalu appeared to expose a rift within the developing-country bloc on responsibility for dealing with climate change. Tuvalu called for discussions on a legally binding amendment to the 1997 Kyoto Protocol that would set targets for reductions in greenhouse gas emissions for major emerging economies such as China, starting in 2013.<br/><br/>The move – backed by dozens of the poorest countries most vulnerable to climate change was blocked by China, India, Saudi Arabia and other large developing countries. The row exposed a rare faultline in the G77 bloc of developing nations, which until now has insisted that rich countries caused global warming and so should shoulder the burden of mitigating it.China tried to downplay the row, insisting the developing world was unified.<br/><br/>India in the meantime made it clear it would not convert its domestic carbon reduction pledges into a globally binding pact. Senior Indian negotiator Mr. Chandrashekar Dasgupta said has made this statement at the climate change meet at Copenhagen Dasgupta's remarks came after US special envoy on climate change, Todd Stern, said that emerging countries like India, China and South Africa would not be given a pass on carbon emissions and that they needed to wrap up their significant proposals into an international agreement.<br/>
