On 28 November 2024, Europol and the law enforcement authorities of Singapore signed a Working Arrangement to strengthen their cooperation in preventing and combating serious crime and terrorism. This Working Arrangement paves the way for further negotiations on related implementing agreements, such as a SIENA Memorandum of Understanding or a Liaison Agreement.

A Memorandum of Understanding on SIENA would allow law enforcement authorities from Singapore to connect with law enforcement agencies from over 70 countries. Under a Liaison Agreement, Singapore could second one or more liaison officers to Europol, adding to the current network of over 300 liaison officers from EU Member States, third countries, and international organisations hosted by Europol.
