During the COVID-19 pandemic, North Korea has grown increasingly isolated as the regime of Kim Jong Un sealed borders and clamped down on the flow of people, information and goods entering and leaving the country. While these recent measures are extreme, they follow a familiar pattern in the DPRK, with periods of international expansion followed by a sharp contraction.  

One area in which this cycle has been particularly noticeable is international education. The number of overseas-educated North Koreans is not very large (there are no exact figures; the most recent data from UNESCOcounts 1,153 North Korean tertiary-level students abroad)
