Thai exporters have been hit hard the past few years, especially in the seafood sector after the US downgraded Thailand from the Tier 2 Watch List to the lowest level, Tier 3, in its 2014 Trafficking in Persons (TIP) report. The EU also issued a yellow card to Thailand for accusations of Illegal, Unreported and Unregulated (IUU) fishing here.
Mr Vallop said the new law will have a broader effect on Thai exports than any other trade barrier because it covers all goods.
He said Thai labour-intensive industries such as garments will be affected the most because they rely heavily on migrant workers, whose use might be considered unacceptable
