Authorities in South Korea have pledged to improve conditions for the country’s 200,000 migrant workers . A woman from Cambodia was found dead living in a green house sub- zero conditions.

Her death is the latest in a series of human rights investigations involving migrant workers in the country. Most of them come from south East Asia. Seventy percent are charged rent for basic shelter such as a greenhouse or a shipping container even during the hash winter.

They are also tied to their employer in a system described by campaigners as a form of modern- day slavery. After decades that have seen little change, it seems their plight has finally been recognized.
