The Indonesian and French Navies conducted a joint exercise in the Sunda Strait on Monday.
Three Indonesian warships and two French frigates FS Vendemiaire and a nuclear-powered submarine FS Emeraude took part in the joint exercise.
According to the Navy's Fleet I Command, this exercise is a form of supervision for ships from other countries entering Indonesian waters, particularly the Indonesian Sea Channel (ALKI) I or the Malacca Strait.
"Three Indonesian warships, namely KRI Barakuda-633, KRI Tenggiri-865 and KRI Cakalang-852 were involved in the drills," said Commander of the KRI Barakuda-633 Faisal Yanova Tanjung in an official statement.
"The French ships will continue their voyages after the joint exercise," Tanjung added.
Chief of Fleet Command I Rear Admiral Abdul Rasyid said the naval exercise also serves as military diplomacy. "We hope it will strengthen our international relations," said Rasyid.
