Prime Minister Prayut Chan-o-cha on Monday threatened to arrest hundreds of thousands of migrant workers if they fail to register themselves with the authorities by June 30, The Straits Times reported. An estimated 698,675 workers have until June 30, when the law is to be enforced, to register, which will allow them to stay in the country for another two years. Tens of thousands of migrant workers, most of them from Myanmar, fled from Thailand last year in fear after the military government adopted a tougher policy on migrant workers. The policy was postponed following criticism from human rights activists.  Thailand’s policies — whether it be the registration program, memorandum of understanding agreement or nationality verification — also need to be simpler, inexpensive and accessible for migrants, writes Ruji Auethavornpipat for East Asia Forum.
