Malaysia will seal a security pact with China and Vietnam that involves exchanges of information on human trafficking syndicates to curb cross border crime, its home minister Hishammuddin Hussein said on Monday.

"The agreement is also crucial in studying the flow of manufactured goods in the context of trade which can sometimes be interpreted as goods that pose a nuclear threat, for example," he was quoted by state news agency Bernama as saying.

"We should realise that transnational crime is now one of the major threats facing the world today, far bigger than the threat to the global system compared to double-dip recessions, political uprising in the Middle East or even earthquakes and tsunamis," he said.

He said he would travel to China and then to Vietnam to sign an agreement in the next several months on human trafficking, worker and student visa and the bilateral security relations.

According to him, Malaysia had inked an agreement with Saudi Arabia for a security partnership in April 2011 and a memorandum of understanding to curb and combat transnational crime with the United Kingdom three months later.
