U.S. Secretary of State Condoleezza Rice and U.S. ambassador to the U.N. John Bolton say they are confident that China will enforce U. N. sanctions against North Korea because of Pyongyang's claimed nuclear test last week.
The resolution bans Pyongyang from importing or exporting some military hardware, and requires U.N. members to search vessels going to or coming from North Korea. It also aims to have some affect on leader Kim Jong Il's elite by banning sales of luxury goods to the country.
Although China voted for the measure, Beijing's U.N. ambassador Wang Guangya says China opposes the cargo inspections stipulated in the resolution. He warned countries against taking what he called "provocative steps."
But Rice and Bolton both said in television interviews on Sunday that they believe China will carry out its responsibilities in such things as ship inspections, since it had signed off on the resolution.
North Korea's U.N. ambassador Pak Gil Yon rejected the resolution Saturday and walked out of the Council chamber following the vote. He said Pyongyang considered further U.S. pressure a declaration of war.
North Korea's neighbors have welcomed the measure.
South Korea said it would "faithfully implement" the resolution, and Japanese Prime Minister Shinzo Abe said Tokyo is considering imposing additional sanctions on its own.
However, the chairman of South Korean President Roh Moo-hyun's Uri party says Seoul should not participate directly in interdicting North Korean shipping, saying such action could spark an armed conflict.
U.S. Secretary of State Condoleezza Rice will visit China, South Korea and Japan this week to discuss enforcement of the resolution.
