NEW DELHI (PTI):  Navies of India and Indonesia have begun a 12-day coordinated patrol in the Andaman Sea and Straits of Malacca in reflection of their fast-expanding cooperation.

The Indian Navy units of Andaman and Nicobar Command (ANC) are participating in the joint mission from June 13 to 24, officials said.

It is the first such drill between the two sides after the COVID-19 pandemic.

"It includes a visit by the Indonesian Navy units to ANC at Port Blair from June 13 to 15 followed by a sea phase in the Andaman Sea and a visit by Indian Navy units to Sabang (Indonesia) from June 23 to 24," an Indian Navy spokesperson said.

The two navies have been carrying out the coordinated patrol along their International Maritime Boundary Line (IMBL) since 2002.

"This has helped build understanding and interoperability between both the navies and has facilitated measures to prevent and suppress Illegal Unreported Unregulated (IUU) fishing, drug trafficking, maritime terrorism, armed robbery and piracy," the spokesperson said.
