BURMA SAYS DEBT SERVICE RATIO FALLS TO 48.8 PCT Burma's debt service ratio will have fallen to 48.8 pct in the fiscal year to end-March 1987 from 50 pct in 1985-1986, the official Council of People's Inspectors (CPI) reported. Western diplomats in Rangoon estimate the figure at above 70 pct and say the country can no longer depend on foreign exchange reserves to cover more than a few weeks' imports. The CPI, which oversees government spending, said in its latest report to parliament that foreign currency reserves fell to a record low of 407.9 mln kyats in September 1986 from 430.3 mln in March 1986. Earlier figures were not available. Debt servicing cost Burma 1.62 billion kyats in 1985-1986 while foreign exchange earnings -- export revenues plus loans and aid -- totalled 3.23 billion kyats in the same period, the council said. Later figures were not available. Burma, which diplomats here say now has foreign debts of up to 3.4 billion dlrs, has applied to the United Nations to be reclassified as one of the world's least developed countries in order to qualify for softer loan and grant aid.
