The Council of Ministers on Friday approved a draft sub-decree barring the production of materials used in the making of chemical, nuclear or biological weapons.

Cambodia’s constitution already prohibits the manufacture, use or storage of chemical, nuclear and biological weapons under articles 9 and 54.

The sub-decree was prepared by the Defence Ministry’s Chemical Weapon National Authority as a mechanism to control the production and use of chemicals in line with international treaty obligations.

It follows a draft law introduced in 2009 that similarly barred the use, manufacture or storage of such weapons.

“Our constitution has prohibited the use of chemical, nuclear, biological and radioactive [weapons], but we have prepared this sub-decree as an addition,” said government spokesman Phay Siphan today.

Chum Sambath, an undersecretary of state at the Defence Ministry, said Cambodia has no chemical or nuclear weapons and would never produce them.

“We don’t need to produce chemical weapons because we have no intention to invade any country,” he said.

Minister of Defence Tea Banh could not be reached for comment today.

In 2005 Cambodia signed the Chemical Weapons Convention, a global initiative by the Organization for the Prohibition of Chemical Weapons.
