Piracy in the Strait of Malacca
Piracy in the Strait of Malacca has long been a threat to ship owners and the mariners who ply the 900 km-long (550 miles) sea lane. In recent years, coordinated patrols by Indonesia, Malaysia, Thailand, and Singapore along with increased security on vessels have caused a sharp downturn in piracy.
