Samoa's prime minister says Samoa and other Pacific island nations are looking to South Korea to protect the region in the event of a nuclear missile attack by North Korea.
Tuilaepa Sailele Malielegaoi said this was among topics discussed at recent talks held in the South Korean capital Seoul.
He told reporters at his weekly media briefing on Friday it was hoped there'd be a plan on the issue soon.
Tuilaepa, who is chair of the Pacific Islands Forum, referred to the leadership of North Korea as "a bit off in the head".
He said the issue was of major concern particularly as another test was launched by Pyongyang during the Seoul visit.
