Trafficking in persons:
current situation: Thailand is a source, transit, and destination country for men, women, and children subjected to forced labor and sex trafficking; victims from Burma, Cambodia, Laos, China, Vietnam, Uzbekistan, and India, migrate to Thailand in search of jobs but are forced, coerced, or defrauded into labor in commercial fishing, fishing-related industries, factories, domestic work, street begging, or the sex trade; some Thai, Burmese, Cambodian, and Indonesian men forced to work on fishing boats are kept at sea for years; sex trafficking of adults and children from Thailand, Laos, Vietnam, and Burma remains a significant problem; Thailand is a transit country for victims from China, Vietnam, Bangladesh, and Burma subjected to sex trafficking and forced labor in Malaysia, Indonesia, Singapore, Russia, South Korea, the US, and countries in Western Europe; Thai victims are also trafficked in North America, Europe, Africa, Asia, and the Middle East
tier rating: Tier 2 Watch List - Thailand does not fully comply with the minimum standards for the elimination of trafficking, and is not making significant efforts to do so; in 2014, authorities investigated, prosecuted, and convicted fewer traffickers and identified fewer victims; some cases of official complicity were investigated and prosecuted, but trafficking-related corruption continues to hinder progress in combatting trafficking; authorities’ efforts to screen for victims among vulnerable populations remained inadequate due to a poor understanding of trafficking indicators, a failure to recognize non-physical forms of coercion, and a shortage of language interpreters; the government passed new labor laws increasing the minimum age in the fishing industry to 18 years old, guaranteeing the minimum wage, and requiring work contracts, but weak law enforcement and poor coordination among regulatory agencies enabled exploitive labor practices to continue; the government increased efforts to raise public awareness to the dangers of human trafficking and to deny entry to foreign sex tourists (2015)
