South Korea warns North Korea over nuclear test

South Korea warned on Wednesday morning that it could abandon its policy of pursuing engagement with North Korea if the communist neighbor goes ahead with a nuclear test. South Korea said earlier in the day that the North should take full responsibility for all consequences if it put into action its threat to conduct a nuclear test. Asked to elaborate on what the consequences would be, Foreign Ministry spokesman Choo Kyu-ho told the Associated Press that a nuclear test "could bring about a shift" in South Korea's policy of engagement with Pyongyang.
