Indeed the national security adviser was in Pyongyang briefly in August. The primary focus of the mission, from our perspective, was to secure the release of Pastor Lim, which they were successful in doing, so we were very pleased with that outcome.
He did have discussions with representatives of the North Korean foreign ministry, and in the course of those raised the concerns we have regarding North Korean proliferation and the grave threat it poses to peace and security in the region. There was a discussion around those issues.
I don't have the full transcript of the discussion, but from memory the response of the North Koreans was what we've heard many times before.
