Fiji's ports have been cleared to operate under the new International Ship and Port Security Code which comes into force on the first of July.
The new rules are designed to ensure that terrorists do not use ports and ships to carry out their attacks.
The rules include the tightening of security measures at the ports on entry with three levels of alert, the final being a declaration that the military or police should intervene because a port is considered at risk from terrorists.
The new international rules are aimed preventing a hijacked ship being used to carry a nuclear "dirty bomb" into one of the world's main ports or to launch missiles at a coastal city.
The measures specify what security equipment each ship and port must have, and oblige them to draw up and enact adequate security plans, and to designate officers to ensure these are complied with.
The United States Coast Guard says it intends to board every ship that does not comply with the rules on its first entry to an American port from July the first.
