AKIPRESS.COM - North Korea's overseas labor force is a significant source of revenue but more countries are trying to ban Pyongyang's state-sanctioned workers, according to UPI.

In Mongolia, the treatment of North Korean workers is under scrutiny after the UN's International Labor Organization raised concerns about their rights.

There is currently no new ban on the presence of forced labor within Mongolia's borders, but more than 1,000 North Koreans are reportedly working in factories, construction sites, restaurants and medical clinics.

The labor is in demand, according to one broker for construction firms in the Mongolian capital of Ulaanbaatar.

North Koreans are inexpensive employees and earn about $700 monthly, but receive only $150-200 after donating the rest to the Kim Jong Un regime.

Some are even experiencing a cut in pay. One North Korean who has been in Mongolia since 2011 said his pay was reduced although he works 12 to 14 hours daily.

The worker said he has been unable to send funds to his wife and daughter in Pyongyang.
