In 1950, with the outbreak of the Korean War, the United States began an aid programme which resulted in fully stabilized prices by 1952. Economic development was encouraged by American economic aid and programmes such as the Joint Commission on Rural Reconstruction, which turned the agricultural sector into the basis for later growth. Under the combined stimulus of the land reform and the agricultural development programmes, agricultural production increased at an average annual rate of 4 per cent from 1952 to 1959, which was greater than the population growth, 3.6 per cent.
