United States Vice President Joe Biden on Friday urged Asean and China to quickly reach agreement on a code of conduct on maritime disputes in the South China Sea.
He called on all parties invovled to "reject coercion, intimidation, threats and use of force".
"We are encouraged by the agreement to start discussions on a code of conduct and we hope to see it followed through in the upcoming weeks," he said at the Istana.
Four Asean member states - the Philippines, Vietnam, Malaysia and Brunei - have territorial claims in the sea which overlap with China's.
Mr Biden was speaking after he called on Prime Minister Lee Hsien Loong during his three day visit to Singapore. He also called on President Tony Tan and met former prime minister Lee Kuan Yew.
PM Lee said Singapore welcomes the US to play a constructive role in the region.
Both men also discussed the Trans Pacific Partnership during their meeting, referring to talks around a free trade agreement which Japan joined as its 12th member this week.
Mr Biden said: "The TPP is not only ambitious, it is doable."
