U.S. Deputy Ambassador Rosemary DiCarlo said U.N. Resolution 1874 passed by a 15-0 vote, thereby approving an embargo of North Korean arms and an enhanced ban on imported weaponry, CNN said.
"This resolution provides a strong and united international response to North Korea's test of a nuclear device," DiCarlo said.
North Korea intensified international opposition to its nuclear program by conducting a nuclear test in May along with test-firing six short-range rockets, CNN said.
Meanwhile, South Korean Foreign Minister Yu Myung-hwan told the Yonhap news agency the United States is considering imposing additional sanctions against North Korea over some international crimes Washington has let pass in recent years.
