Foreign ministry officials of South and North Korea had contact in Switzerland last month where the North made it clear that it's not interested in inter-Korean dialogue.
 
Choe Kang-il, deputy director general for North American affairs at North Korea's foreign ministry, attended a security conference in Switzerland for three days from September eleventh, a week after the North's sixth nuclear test. 
 
Former and current officials of the U.S., China, Japan and Russia also attended the meeting, while South Korea sent a deputy director general-level official and a scholar.
 
A diplomatic source told KBS that during the encounter with South Korean delegates, the North Korean delegation repeated its position that the North will not return to dialogue unless the U.S. ends its hostile policy on Pyongyang, by stopping all joint military exercises with South Korea and lifting all sanctions. 
 
Meanwhile, Choe Son-hui, director-general of the North American affairs bureau at Pyongyang's foreign ministry, plans to attend the 2017 Moscow Nonproliferation Conference set to open on Thursday for a three-day run. 
 
The two Koreas could make contact again at the conference as South Korea is mulling sending a director-level official.
