On Thursday, June 19, in Washington, D.C., I gave a lecture and participated in an extensive Q & A on the subject of post-purge North Korean Special Economic Zones in China. The Q & A for the event, hosted by the Korea Economic Institute as part of its Academic Paper Series, starts at about minute 45 of the above video; the pdf of the working paper itself is available here. Journalists who would like to speak or correspond with me about the subject further can contact me at a.cathcart@leeds.ac.uk.
