The United States said today it halting the use of anti-personnel mines apart from in the tense No Man's Land between the Koreas, a step closer to compliance with a global convention.
On the 20th anniversary of then president Bill Clinton's pledge to back the eventual elimination such weapons, Barack Obama's administration said it was "aligning its policy" on anti-personnel landmines (APLs) with the Ottawa Convention.
The US "will not use APL outside the Korean peninsula," national security spokeswoman Caitlin Hayden said.
Washington would also "undertake to destroy APL stockpiles not required for the defense of the Republic of Korea," she added.
The United States would also neither assist nor encourage anyone outside the region to use such mines.
The move brings the United States closer than ever to adhering to the Ottawa Convention, the international treaty prohibiting the use, stockpiling, production, and transfer of anti-personnel landmines.
The announcement, made as Obama headed to the United Nations General Assembly, mirrored intentions foreshadowed by Washington at a conference in Mozambique's capital Maputo in June aimed at ultimately ensuring no armed forces use anti-personnel mines by 2025.
Obama was expected to touch upon the issue when he addresses the annual meeting of the Clinton Global Initiative, an arm of the former US leader's charitable foundation, in New York.
A senior US official told AFP that only the "unique circumstances" of the Cold War frontier between North and South Korea stood between the United States and the further elimination of the use of land mines.
Washington had only been able to pinpoint a single use of a land mine by its forces in a military situation - apart from between the two Koreas - in the last 20 years, though would not say where it took place, the official added.
In 2009, Washington said it was reviewing its position on landmines but - along with great power rivals China and Russia - has failed to sign the Ottawa Convention.
Nuclear powers India and Pakistan - which like the two Koreas have a hot frontier - have not signed up either, nor has arch-foe Iran.
Long-standing critics of the US policy say Washington's rivals are waiting on the United States to move before they do likewise.
Today's move could up pressure on states to ban landmines, despite festering territorial disputes breaking out across eastern Europe and the Middle East.
"The United States remains deeply concerned about the humanitarian effects of anti-personnel landmines," State Department spokeswoman Jen Psaki said.
