Washington – The International Monetary Fund (IMF) will not disburse a second 3 billion dollar installment of its loan to financially beleaguered Indonesia before April, an IMF spokeswoman said Friday.

The delay of the loan installment, which forms part of a 40 billion dollar international rescue deal, came as the IMF and the U.S. government expressed dissatisfaction with Indonesian President Suharto's economic policy.

"The IMF management aims at the speedy conclusion of the review discussions as soon as the basic conditions are met and the required changes in a few macroeconomic assumptions of the program can be made," the spokeswoman said.

"Assuming this can be achieved, and given the existing IMF procedures," she said, "the date of the Executive Board discussion of the conclusion of this program review could not be expected before April."

The IMF originally had planned to approve a handover of the second installment of its loan at its Executive Board meeting March 15.

The IMF and the U.S. government are dissatisfied with what they see as Suharto's noncommittal attitude toward full implementation of a program he and the IMF agreed upon in January to revamp the Indonesian economy.

It is feared that postponing the disbursement could aggravate Indonesia's economic and social turmoil, the result of the rupiah's rout and ensuing financial unrest.

Suharto's idea of pegging the value of the rupiah to the U.S. dollar is believed to stand in the way of the economic reform program. Former U.S. Vice President Walter Mondale, who visited Indonesia earlier this week as a special envoy of U.S. President Bill Clinton, failed to dissuade Suharto from the planned monetary policy.
