SINGAPORE, Dec 30 (AFP) - Singapore on Thursday called on the Association of Southeast Asian Nations (ASEAN) to hold a meeting to mount a coordinated relief effort to deal with the Asian tsunami catastrophe. The leaders of Malaysia, Thailand and Indonesia -- the three ASEAN countries hit by the tsunamis -- have agreed a meeting should be convened, Prime Minister Lee Hsien Loong said in a press conference. Lee said the meeting should work on setting up an emergency relief fund and appointing a special representative to oversee the relief efforts. A date for the meeting has not yet been set but it could possibly include China, Japan, South Korea, the United Nations and the World Health Organisation, Lee said. "The amount is so enormous that no country can do it alone," Lee said, referring to the vast financial resources needed to help rebuild the affected areas and help survivors of Sunday's tragedy. "It has to be an international effort," he said as his government raised its contribution for tsunami-hit nations to 25 million Singapore dollars (15 million US) with more aid having been despatched to Indonesia and Thailand. "We are part of this region where it has happened and we have to respond," Lee said. Lee said the proposed ASEAN meeting could also include the United States, Australia and New Zealand and the World Bank. A similar initiative involving the US is underway after President George W. Bush announced a "core group" of nations comprising the US, Japan, Australia and India would lead relief efforts. ASEAN comprises Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand and Vietnam. str/bh/mtp
