This thesis aims to study the policy of the second Phibulsonggram regime concerning Vietnamese refugees in Thailand during 1948-1957. The study focuses on factors contributing to the forming of the policy, its implementation and its repercussions on Vietnamese refugees. My study reveals that the implementation of the second Phibulsonggram regime's policy on Vietnamese refugees was more strict than the one carried out by the previous civil government. It also further reveals that the second Phibulsonggram government's policy regarding the Vietnamese refugees was formed in order to serve the purposes of national security and to bring Thailand into closer alliance with the United States of America in relation to the latter's anti-communist policy. These factor led the second Phibulsonggram government to increasingly implement more strict policy regarding the Vietnamese refugees who were disappointed with such policy and they eventually protested against it.
