Indonesia and Singapore signed on Tuesday a bilateral extradition agreement, a move that Jakarta expects to help authorities in their effort to bring to justice people accused of stashing offshore billions of dollars in state money.

Senior cabinet ministers from both countries also signed bilateral agreements covering airspace and defense in a ceremony aired on Indonesia's State Secretariat YouTube channel.

The signings follow a meeting between President Joko "Jokowi" Widodo and Singapore Prime Minister Lee Hsien Loong on the Indonesian island of Bintan as part of their annual leaders' retreat.
