North Korean leader Kim Jong Un has ignored recent peace overtures from Seoul but he's due on Tuesday to hold a formal dialogue with his southern neighbor for the first time in more than two years.
The sudden interest in talks may have something to do with Pyongyang's nuclear arsenal.
"The North has made significant advances in its ballistic missile and nuclear weapons program so I think they feel a bit more willing to engage in talks now that they've actually demonstrated an incipient nuclear capability that can strike the U.S.," said Taylor Fravel, associate political science professor at MIT.
In November, the rogue state launched a new type of intercontinental ballistic missile capable of reaching the U.S. mainland. Known as the Hwasong-15, it can fly over 13,000 kilometers, or 8,080 miles.
Speaking on the sidelines of the UBS Greater China Conference in Shanghai, Fravel said he isn't expecting much from Tuesday's discussion, which he believes will largely focus on potential North Korean participation at the Winter Olympics in the South Korean city of PyeongChang.
