Japan does not plan to support a document circulated among U.N. members that calls for a ban on nuclear weapons, after the United States, its security ally and provider of nuclear deterrence, urged it not to, government and diplomatic sources said Thursday.

The paper has been distributed by Austria, which hosted an international meeting on the humanitarian impact of nuclear weapons in December. Hoping to add impetus to the debate on banning nuclear weapons, Austria plans to submit it to a U.N. conference held from next month to review the Nuclear Nonproliferation Treaty.

As the only country to have suffered atomic bombing, Japan has pushed for the adoption at the U.N. General Assembly every year of a resolution calling on states to take action toward the elimination of nuclear weapons.
