The United Nations Security Council has voted to impose new sanctions on North Korea over its most recent and largest nuclear test in September.
The 15-member council on Wednesday unanimously adopted a resolution, which curbs Pyongyang's biggest export, coal, by at least 60 percent. It also bans the country's copper, nickel, silver and zinc exports.
The resolution, spearheaded by the United States and passed by a 15-0 vote, condemns "in the strongest terms" North Korea's latest nuclear test on September 9.
"Sanctions are only as effective as their implementation," outgoing UN Secretary General Ban Ki-moon told the Security Council after the vote, adding, "It is incumbent on all member states of the United Nations to make every effort to ensure that these sanctions are fully implemented."
On September 9, North Korea said that it had conducted a successful "nuclear warhead explosion" test, saying it was meant to counter US hostility.
Pyongyang's state media said the test had achieved its goal of being able to fit a miniaturized nuclear warhead on a rocket.
"Our nuclear scientists staged a nuclear explosion test on a newly developed nuclear warhead at the country's northern nuclear test site," a North Korean TV presenter said.
North Korea has been under a raft of UN sanctions over its nuclear and missile tests.
Pyongyang says it will not abandon its nuclear “deterrence” unless Washington ends its “hostile” policy toward the country.
