South Korea will impose new unilateral sanctions against nuclear-armed Pyongyang, a report said Sunday, in Seouls latest effort to pressure the North after a series of weapons tests that have sent regional tensions surging.
The move comes after a rare visit to North Korea by a senior UN official, who called for dialogue between Pyongyang and the international community to avert a potentially catastrophic "miscalculation" in the high-stakes nuclear crisis.
