Malaysia urged Asian shipping lines today not to compromise on security measures amid growing terrorist threats and said it would cooperate with the United States on container security.

"Shipping lines are now being compelled to take a relook at the way cargoes are loaded or what cargoes are carried, where, why and how," said Transport Minister Ling Liong Sik, opening a two-day Asia Maritime and Logistics Conference here.

"There is also the need to review documents that accompany the cargo. The search for greater maritime safety and security demands a firm hand and quick decisions and there can be no compromise on this," Ling said.
