Tzinista [China] and other trading places, it receives silk, aloes, cloves, sandalwood and other products, and these again are passed on to marts on this side, such as Male [Malabar or South West Indian coast] ... and to Calliana [Kalyana]... This same Sielediba then, placed as one may say, in the centre of the Indies and possessing the hyacinth [sapphire] receives ... and in turn exports to them, and is thus itself a great seat of commerce." Independence to 1977 Sri Lanka was ahead of many Asian nations and had economic and social indicators comparable to Japan when it gained independence from the British in 1948. Sri Lanka's social indicators were considered "exceptionally high". Literacy was already 21.7% by the late 19th century. A Malaria eradication policy of 1946 had cut the death rate from 20 per thousand in 1946 to 14 by 1947. Life expectancy at birth of a Sri Lankan in 1948 at 54 years was just under Japan's 57.5 years. Sri Lanka's infant mortality rate in 1950 was 82 deaths per thousand live births, Malaysia 91 and Philippines 102. With its strategic location in the Indian Ocean Sri Lanka was expected to have a better chance than most other Asian neighbors to register a rapid economic take-off and had "appeared to be one of the most promising new nations." But the optimism in 1948 had dimmed by 1960, due to wrong economic policies and mismanagement. East Asia was gradually overtaking Sri Lanka. In 1950 Sri Lanka's un-adjusted school enrolment ratio as a share of the 5-19 year age group was 54%, India 19%, Korea 43% and the Philippines 59%. But by 1979 Sri Lanka's school enrollment rate was 74%, but the Philippines had improved to 85% and Korea was 94%. Sri Lanka had inherited a stable macro-economy at independence. A central bank was set up and Sri Lanka became a member of the IMF entering the Bretton Woods system of currency pegs on August 29, 1950. By 1953 exchange controls were tightened with a new law. The economy was then progressively controlled and relaxed in response to foreign exchange crises as monetary and fiscal policies deteriorated. Controls and restrictions in 1961-64 were followed by partial liberalization in 1965–70. Controls were continued after a devaluation in the wake of 1967 Sterling Crisis. Controls were tightened from 1970 to 1977 alongside the collapse of the Bretton Woods system. "In
