Jakarta, Sep 6 (IANS): Indonesia and the Philippines have signed a memorandum of understanding (MoU) on intensifying maritime security cooperation on the waters of their border areas.

The MoU was signed during the state visit to Indonesia by Philippine President Ferdinand Marcos, who met his Indonesian counterpart Joko Widodo at the Bogor Palace in West Java on Monday, reports Xinhua news agency.

On Sunday, Marcos began his three-day visit to Indonesia.

"We have agreed to review our security agreements in terms of border crossing and border patrols," Widodo said in a virtual press conference aired by his presidential secretariat office.
