While forced labor exists throughout the world, nowhere is the problem more pronounced than here in the South China Sea, especially in the Thai fishing fleet, which faces an annual shortage of about 50,000 mariners, based on United Nations estimates. The shortfall is primarily filled by using migrants, mostly from Cambodia and Myanmar.
Many of them, like Mr. Long, are lured across the border by traffickers only to become so-called sea slaves in floating labor camps. Often they are beaten for the smallest transgressions, like stitching a torn net too slowly or mistakenly placing a mackerel into a bucket for herring, according to a United Nations survey of about 50 Cambodian men and boys sold to Thai fishing boats. Of those interviewed in the 2009 survey, 29 said they had witnessed their captain or other officers kill a worker.
