UN Secretary-General Ban Ki-moon expressed disappointment at the lack of progress at a 190-nation conference in Bali, where delegates were deadlocked over a plan to start talks on a new UN treaty. Ban made an 11th hour appeal for delegates to make compromises, particularly regarding developing nations' demands for more assistance from wealthy countries to combat climate change. If the deadlock is resolved, the conference would kick off two years of negotiations on a comprehensive new global treaty to replace the Kyoto Protocol after 2012, involving the US and all developing countries. Ban urged delegates to deliver a successful outcome for the world's people. Indonesian President Susilo Bambang Yudhoyono also urged delegates, emphasizing the importance of having a clear road map to reach their envisioned destination. He expressed concern that the project could fail if the wording is not right, stressing that the world is closely observing and pleading with them not to disappoint.
