ドイモイ
He is known throughout southern Vietnam as Dr. Rice (as in a medical doctor) because of a popular television show which he presented that taught farmers better techniques for growing and cultivating rice. He was also instrumental in the eradication of the brown planthopper bug which, throughout the 1970s was destroying paddy rice. Part of the problem in eradicating the bug infestation was the type of collectivization imposes on the farmers of southern Vietnam. He also helped to bring about reforms in the early 1980s that can be seen as catalysts to the "Doi Moi" reforms of 1986.
