Singapore and the United States have reaffirmed their wide-ranging cooperation on defence and security, trade and investment, as well as cyber security, said Minister for Foreign Affairs Vivian Balakrishnan after a phone conversation with US National Security Adviser Jake Sullivan on Tuesday.

Singapore's Ministry of Foreign Affairs (MFA), in a statement, said Dr Balakrishnan expressed support for the US' leadership role in tackling important global issues such as the Covid-19 pandemic and climate change, and expressed Singapore's readiness to cooperate with the US on these fronts.

In a Facebook post yesterday morning, Dr Balakrishnan congratulated Mr Sullivan on his appointment, adding that he looked forward to working together with him.

Dr Balakrishnan last met Mr Sullivan during his visit to Singapore a couple of years ago. "Jake is a good friend of Singapore, and familiar with our strong and robust cooperation over the years in the defence, security and economic spheres," said Dr Balakrishnan.

"The world has changed rapidly since our last meeting, and we discussed several new areas of collaboration, including in cyber security and the digital economy."

Dr Balakrishnan and Mr Sullivan also exchanged views on international and regional developments, and agreed to work together to expand US engagement of the Asia-Pacific region, especially Asean, said MFA.

Dr Balakrishnan said he welcomes US commitment to "expand and strengthen cooperation with Asean, especially in trade and investment".
