The Marshall Islands is to lodge an appeal in a case against the United States over nuclear disarmament.
The islands were the scene of massive US nuclear tests in the 1950s and it is suing the US and eight other nuclear-armed countries for failing in their obligation to negotiate nuclear disarmament.
A lawyer for the Marshall Islands, Laurie Ashton, says the team is disappointed in last week's dismissal of its case by the US District Court which found the breach of the Treaty on Non-Proliferation of Nuclear Weapons and the subsequent harm claimed by the Marshall Islands was speculative.
She says the Marshall Islands also disagrees with Judge Jeffrey White's findings that the court could not order the US to comply with the treaty and could not provide redress from the harm that's claimed.
"We will go as far as legally, possibly we can go. We are in it to win it and we are in it to the end and we appreciate the bravery of the Marshall Islands and we're not going anywhere."
Ms Ashton says the US Court decision will have very little effect on the Marshall Islands' cases against Pakistan, India and Britain being brought in the International Court of Justice in The Hague
