A summit of South-East Asian nations failed Sunday to resolve a border conflict between Cambodia and Thailand, with the sides agreeing to continue talks on the contentious issue at the level of foreign ministers. "The foreign ministers of Cambodia and Thailand will stay another day to work with the foreign minister of Indonesia," Cambodian Prime Minister Hun Sen said. Hun Sen and Thai Prime Minister Abhisit Vejjajiva met Sunday on the sidelines of the 18th Association of South-East Asian (ASEAN) summit for talks on their border conflict, according to a report of the German Press Agency "DPA". The meeting was hosted by Indonesian President Susilo Bambang Yudhoyono, chair of the summit, who is pushing ASEAN's regional peace-making role.
