The Cook Islands has become the latest state to formally join the Treaty on the Prohibition of Nuclear Weapons. The necessary paperwork was handed in at the United Nations by Ms. Siai Taylor from the Ministry of Foreign Affairs and Immigration.
While other states have ratified the Treaty, the Cook Islands has acceded, a mechanism for states to join the Treaty who did not previously take part in negotiations.
The Cook Islands has become the second Pacific island nation to join the Ban Treaty, following Palau completing ratification earlier this year.
There are now 15 states which have ratified or acceded to the Treaty, which will come in to force once 50 states have completed the process.
