Ships from 13 countries and observers from 20 countries are taking part in the exercise which began earlier this week and will end on Friday.
It comes two weeks after China took control of Gwadar, a strategic Pakistani Arabian Sea port, from Singapore’s PSA International, AFP reported.
Pakistan’s navy said in a statement that the drill is aimed at “information sharing, mutual understanding and identifying areas of common interest.”
The manoeuvres – the fourth since 2007 – will also help develop and practise response tactics, techniques and procedures as well as improving cooperation between navies, the statement said.
One of the main objectives is to “display united resolve against terrorism and crimes in maritime domain,” it said.
“All the nations participating in the AMAN have a common objective of ensuring peace and stability in the maritime arena to provide freedom of navigation and uninterrupted flow of trade,” the Pakistan navy statement said.
The American destroyer USS William P. Lawrence was among the ships taking part, along with vessels from Australia, Britain, Italy, Japan, Malaysia and Turkey. Russia and Germany are among the observers.
