North Korea's reclusive supreme leader, Mr. Kim Jong Il, has ventured to Russia to meet President Dmitry Medvedev and discuss regional affairs. Mr. Kim repeated his readiness to return to the stalled Six-Party Talks "without preconditions" while Mr. Medvedev reportedly offered North Korea partnership in a pipeline project that would transport Russian energy resources to the Asian market.

Neither the nuclear negotiations nor the pipeline is likely to occur anytime soon. But the meeting itself is a sign of shifting regional political dynamics: Moscow seeks to re-establish itself as a player in Northeast Asia and Mr. Kim is trying to maximize his position if nuclear talks resume.

Mr. Kim last visited Russia nine years ago, when he met Mr. Vladimir Putin, then president and now prime minister. Since then, Pyongyang's diplomacy — ever opportunistic — has focused more on South Korea, at least when there was a leader more sympathetic to North Korea in the Blue House. It also has tried to approach the United States, when it sensed the White House was eager to strike a deal, and China, which seeks to lessen strains on the North to achieve regional stability. Pyongyang has always tried to play its diplomatic partners off each other, and Moscow had little to offer North Korea in either monetary or diplomatic terms compared with Beijing or Seoul.
