I found this article on nytimes.com, it states that North Korea will re-join the six party talks if the United States ends its hostility towards the country. Here's an excerpt
North Korea wants bilateral nuclear talks with the United States but would rejoin stalled six-party meetings at once if Washington dropped its ``hostile policy'' toward Pyongyang, the communist state said on Friday.
The article also goes on to give a quote from the official KCNA news agency:
``The DPRK does not care who becomes president in the U.S. and its only concern is what kind of Korea policy the future administration would shape,''
To me, these talks and this article just continue the game of cat and mouse between the United States and North Korea.
