Leaked document shows Obama, Brown and Rasmussen are negotiating in bad faith.

Developing nations taking part in the United Nations climate change conference in Copenhagen have criticised a leaked document which proposes that more power be granted to rich nations.

The US, UK and Denmark are thought to be among those involved in the drafting of the document.

The document says that:

The UN's negotiating role should be sidelined
The legally-binding Kyoto protocol be abandoned.

Developing countries have said that the text is part of a plan by rich nations to set unequal limits on carbon emissions in 2050.

Su Wei, the head of the Chinese delegation, has lashed out at the developed world's largest emitters of greenhouse gases for setting themselves what it called unremarkable - and even deceptive - targets for cuts.

He also said a mooted annual $10bn financial help from rich nations to developing ones as a drop in the ocean.

"If divided by the world population it is less than $2 per person," he said, adding that this would not cover a coffee in the rich world or a coffin in poor countries that are at the sharp end of climate changes.

"Currently the US target is to reduce emissions 4% from the 1995 level, I think for all of us this figure cannot be regarded as remarkable or notable," he said.

Su said all the rich nation targets fell short of the emissions cuts recommended by a UN panel of scientists
