Special Representative for North Korea Policy, on Tuesday and had a further telephone call with Japanese counterpart Kenji Kanasugi on Thursday, according to the Ministry of Foreign Affairs. 

The phone calls were made to share assessments of the situation of the Korean Peninsula following North Korea's New Year address and to discuss future action plans, the ministry said. 

"The South Korean government is having close communications with the U.S., Japan and other concerned countries over North Korean nuclear issues and the latest telephone calls between the top six-party negotiators were also conducted in that regard," the ministry said. 

The conversations came amid growing signs of a possible thaw in inter-Korean relations.
