On Monday, defense ministers from Indonesia, the Philippines and Malaysia launched a Trilateral Maritime Patrol, a joint patrol created to drive back any insurgencies in the region.
Monday's opening ceremony of the joint patrols was held on board an Indonesian warship and was attended by security officials from Singapore and Brunei, who acted as observers.
Indonesia also inaugurated yesterday a maritime command center in the naval base of Tarakan, a town in the province of North Kalimantan on Borneo island, witnessed by defense ministers and army chiefs from the three countries.
Mr Lorenzana, who was speaking on board an Indonesian warship in the waters off Tarakan, North Kalimantan, was referring to the Information Fusion Centre (IFC), which collects and analyses information on vessels at sea around the world before sharing it with global maritime partners.More news: Watch LeBron James unleash dominance upon small children at son's birthday party
Fachroni said the army, navy and air forces would be involved in patrols but more discussions were needed to pin down whether they would be joint or coordinated.
The Philippine military said on Friday that some of the Islamist militants who stormed Marawi City in the south of the country last month may have mingled with evacuees to slip away during the battle that has raged for nearly four weeks.
Mr Ryamizard said that although the patrols are a largely maritime- based operation, air and land military assets will be involved in securing the Sulu Sea, which is located to the north-east of Borneo Island and south-west of the Philippines.

Maritime command centres to coordinate the patrols and information sharing will also be set up in Tawau in Malaysia's Sabah and Bongao in the Philippines.
That Indonesians, Malaysians and other foreigners are fighting alongside Maute militants in Marawi also reinforces the appeal of the southern Philippines to ISIS, which is eyeing territory for expansion beyond the Middle East. "All three countries - Malaysia, Indonesia and the Philippines - are trying to strengthen their border controls and their immigration checks", the Jakarta-based regional terrorism expert said.
Two Indonesians and a Malaysian suspected of planning to cross over by sea in the Malaysian state of Sabah were arrested Friday by Malaysian authorities amid reports that they meant to join Islamic State-linked fighters battling military forces in Marawi.
