SEOUL, Jan. 23 (Yonhap) -- North Korea pledged on Wednesday to end any efforts at denuclearizing the Korean Peninsula, just hours after the U.N. Security Council adopted a resolution condemning the country's December rocket launch, according to North Korea's state-run news outlet.
"Due to the U.S.'s worsening policy of hostility toward North Korea, the six-party talks and the joint September 19 statement were rendered null and the denuclearization of the Korean Peninsula was put to an end," the North's foreign ministry said in a statement carried by the Korean Central News Agency.
"There will be no more discussion over denuclearization of the Korean Peninsula in the future although there will be talks for securing peace and security in the peninsula," according to the statement.
The country will "take physical actions to strengthen self-defense military capabilities including nuclear deterrence," the foreign ministry statement also said.
The statement came just hours after the 15-member council voted unanimously to approve the 20-point resolution, which includes actions to step up sanctions against the communist country.
The resolution is aimed to punish the country for its Dec. 12 launch of a long-range missile, which the outside world suspected was a cover for the country's test of ballistic missile technology.
