This undated photo shows a passport and Chinese documents held by one of the 13 North Korean restaurant workers stationed in China who participated in a successful group defection to South Korea last week. The photo, taken and kept by the restaurant operator, shows that the passport is marked as being for official use, as is commonly issued to North Koreans sent abroad to work. The document shows a foreigner’s registration of resident address in China. China’s foreign ministry had said that the defectors left the country carrying valid passports. (Yonhap)

Sounds like South Korea did exactly what North Korea requested to “those whom it may concern” in North Korean passports.
