Many delegates from developing countries urged Mukahanana- Sangarwe to put forward another text before the next Bonn session from August 2 to 6, and the new draft should reflect proposals and positions of every party with an view to facilitating the line-by- line discussion later on.

De Boer said that he has noticed the main reaction to the text, admitting that "it has shortcomings." But he stressed that the negotiations have not been completely failed, and parties agreed to continue to work on a new draft text for further negotiations.

Martin Khor, director of a think tank for developing countries called the South Centre, said that the draft text no longer referred to any requirement for developed countries to present their reduction pledges within a legally-binding framework like the Kyoto Protocol.

On the future of the Protocol, de Boer said that "the survival of the Kyoto Protocol depends on whether or not the United States is willing to take on targets of the same legal nature as the rest of the industrialized countries."

Since the ministerial-level Cancun meeting is to take place in late November, the schedule of delegates seems rather tight, which was left with only two extra one-week sessions respectively in August and October.

Some observers said it was clear that the chair of AWG-LCA wanted to quicken the negotiations process, but the UN and all parties had to draw lessons from the Copenhagen summit to prevent "the haste makes waste," remembering that "the balance of interests" would be the best approach to step up negotiation.

In an interview with Xinhua during the Bonn session, de Boer said: "I think you can only move forward in a way that addressing the interests of all over countries in a balanced way."

Christiana Figueres, who is to succeed de Boer as UN climate chief early next month also told Xinhua that the Marathon negotiating process refers to "so many different interests represented by all countries and usually the way-out you could find is a balanced package, which would not meet all needs of everyone but at least meet the basic needs of everyone."
