Political relations between Russia and North Korea broke down after the Soviet Union dissolved in the early 1990s and so did military relations. But now the two are discussing resumption on direct military ties. Russian military officers flew North Korea to talk about it even as North Korean leader Kim Jong Il rides an armored train on a secretive journey to meet with President Dmitry Medvedev. The two are scheduled to meet in Siberia. North Korea may be preparing to resume six-party disarmament talks.
