Samoa has signed the United Nation's Arms Trade Treaty which regulates the trade in conventional arms, from small arms to battle tanks, combat aircraft and warships.
A government statement says the treaty will not prevent countries from purchasing or acquiring conventional arms for self defense and security needs.
But it will prevent human rights abusers and violators of the law of war from being supplied with weapons.
Meanwhile, four police officers from Samoa will soon be deployed for the UN peacekeeping mission in Sudan for 12 months.
The officers are Sergeant Sani Afu, Corporal Va'onuu Ai'araisa Nafoi, Corporal John Duvan Fa'anu'uali'i and Constable Ioane Tavai.
