India and China objected on Saturday to a draft 2009 climate deal at UN talks in Bali, saying rich nations should do more to lead the way.
India told a 190-nation meeting that it wanted the final text to strengthen the role of rich nations in providing clean technology and finance to help fight global warming.
"The need of the hour is for enhanced commitments and instead we see a huge watering down," said Indian delegate Chandrasekhar Dasgupta.
"This is a conspiracy," a Chinese delegate said of a draft text presented to delegates on Saturday by the Indonesian hosts of the December 3-4 meeting in Bali.
Many developing nations are unhappy that the draft text cut out a guideline for rich nations to do more and cut emissions of greenhouse gases by 25 to 40 per cent below by 2020.
But China and India, the number two and four emitters of greenhouse gases, want concessions from the rich before committing to join climate talks.
UN Secretary-General Ban Ki-moon urged delegates to break a deadlock over the deal. "Your work is not yet over ... everybody should be able to make compromises," he said. ( Gulf )
