The United States is welcoming efforts by Southeast Asian nations to push Burma's military rulers towards democracy.
But a U.S. embassy spokeswoman says Assistant Secretary of State Christopher Hill also told Malaysian officials the United States is concerned about Burma's delay in implementing democratic reforms.
Malaysia's Foreign Minister, Syed Hamid Albar, says he told Hill he hopes to visit Burma soon.
He said Malaysia, which currently chairs the Association of Southeast Asian Nations (ASEAN), wants the group to take on a larger role since the United Nations special envoy on Burma Razali Ismail resigned.
Hill is in Malaysia as part of an Asian tour that has included stops in South Korea, Japan, China and Vietnam. He will conclude his trip with a stop in Cambodia.
