A law passed by Thailand in February will see a reversion to the old system of conferring semi-regular status through a 'pink card' to illegal migrants once inside. Rights groups warn that this will see a dismantling of the already minimal social safety net for the millions of Myanmar and Cambodians who help to prop up the Thai economy. Many also fear that the new rules will encourage migrants to cross the border illegally, in the knowledge that they will be issued semi-regular status once they arrive.
