Pirate attacks in South China Sea increase
The International Maritime Bureau says there have been 22 attacks in the South China Sea so far this year, compared to 17 last year.
The South China Sea is bordered by Brunei, China, Indonesia, Malaysia, the Philippines, Singapore, Taiwan and Vietnam.
Mr Zahid says state-of-the art technology adopted by the navies of some Asian nations is useless without cooperation in combating piracy.
He says the affected area lies in a triangle between Indonesia's Anambas Islands, Tioman Island off Malaysia and the eastern Singapore Straits.
Pirate attacks in the Malacca Strait, which was once the world's worst piracy hotspot, have declined sharply in recent years because of large-scale coordinated patrols involving Indonesia, Malaysia and Singapore.
