Temporary exchanges between the two Koreas through participation in the 2014 Asian Games in Incheon or in one-time family visits aren't enough to build a sustainable, long-term relationship, said Nicholas Hamisevicz.

Hamisevicz, who is responsible for researching issues related to North Korea affecting the U.S.-South Korea alliance at the Korea Economic Institute of America (KEI), said that instead of having a few events on less weighty political issues, Hamisevicz believes that the two Koreas need to develop methods to have sustained dialogue on deep political, economic, and humanitarian issues.
