He was the President of the Thailand Development Research Institute and later served as Minister of Finance in Surayud Chulanont's military junta. An ethnic Chinese of Hainanese origin,[1] [2] he replaced Pridiyathorn Devakula after Pridiyathorn abruptly resigned.

After graduation, he taught at the Department of Economics at the University of California, Berkeley during 1977–79.[3] He later joined the World Bank in Washington, D.C., where he served from 1979 to 1985.
