SEOUL - South Korea's labour ministry on Wednesday announced a fivefold increase in cash incentives aimed at encouraging North Korean refugees to find jobs.

The refugees will receive a total of one million won (S$1,236) in incentives if they stay at the same workplace for more than six months after receiving state-funded job training.

The cash rewards will be given gradually - 200,000 won after a month of work, 300,000 won after three months and 500,000 won after six months.

The ministry previously provided only a single payment of 200,000 won after nine months.

Government data showed last year that only 42 percent of refugees had found jobs in the South. Some complain of discrimination, others find their work skills unsuitable for their new country.

Almost 18,000 North Koreans have fled their impoverished communist homeland and arrived in South Korea since the 1950-1953 war.

Upon arrival they undergo a mandatory three-month course designed to impart job skills and practical lifestyle tips, such as how to buy a subway ticket or use a credit card.
