US, China said to be discussing choking off North Korean energy

New York

THE US and China are locked in negotiations over curbing North Korea's energy trade in response to its fifth nuclear test last month, according to four diplomats from United Nations Security Council countries with direct knowledge of the talks.

The world's two biggest economies - both of whom can veto any resolution - are discussing restrictions on North Korea's trade in coal, iron ore and crude oil, according to the diplomats, who asked not to be named because the discussions are private. Other nations are also considering separate sanctions against North Korea once the Security Council acts, the diplomats said.
