MINISTRY of Labor and Vocational Training figures show Cambodia sent 1,276 migrant workers to South Korea in the first nine months of 2009, down 17 percent from 1,537 workers over the same period a year earlier. Heng Sour, the ministry’s official in charge of migrant labour relations with South Korea, said last week the drop was due to the effect of the economic crisis on South Korea. “It has not happened only for us, but also for the other 15 countries that send workers there,” he said.
