Koreans Impose Autosanctions

North Korea said Tuesday it considered U.N. sanctions aimed at punishing their homeland for its nuclear test "a wise choice," as Japan and South Korea reported the communist nation might be preparing to impose sanctions on itself.

The North broke two days of silence about the U.N. resolution adopted after its Oct. 9 nuclear test with a statement on the official state news agency, as China warned Pyongyang against "ironical political behavior."

The chief U.S. nuclear envoy, Assistant Secretary of State Christopher Hill, said the North's response was "beyond logic" and admitted that he, "wasn't exactly sure how that would even work."
