South Korea's top nuclear envoy, Cho Tae-yong, urged North Korea Tuesday to take "actions" to assure that it is serious about denuclearization as he began a three-day trip to Washington for consultations on ways to deal with Pyongyang.
"North Korea should show its will for a real denuclearization through actions," Cho, who serves as South Korea's special representative for Korean Peninsula peace and security affairs, told reporters upon arriving.
His trip comes amid renewed efforts to revive negotiations on North Korea's nuclear program following months of sharp military tensions on the peninsula.
Pyongyang is apparently on a charm offensive but Seoul and Washington question its intentions.
