Vietnam's labor authorities have temporarily banned people from 23 wards from applying to work in South Korea after many workers from these wards quit jobs or overstayed in South Korea after their contract expired.
These wards and communes, most of which are in northern Vietnam, each have more than five illegal migrants in South Korea, according to a report by Tuoi Tre newspaper.
Under the ban, people from these wards and communes are not allowed to sit for the Korean language test, Tuoi Tre quoted a labor ministry's decision as saying.
The document said that this measure is necessary to prevent South Korea from re-imposing a ban on recruiting Vietnamese workers.
In August 2011, South Korea halted the Korean language test for Vietnamese workers after finding a number of Vietnamese laborers quit their jobs without proper reasons or overstay their allotted time in South Korea after their work contracts expire.
