(Recasts, new throughout, adds byline) By Alister Bull WASHINGTON, April 9 (Reuters) - The International Monetary Fund said on Monday it had approved the first IMF finance for Lebanon, backing a $77 million emergency loan to help rebuild the country after last year's conflict with Israel. Mohsin Khan, director of the IMF's Middle East and Central Asia Department, told a news conference that the loan, issued as emergency post-conflict assistance (EPCA), would be available to Lebanon within the next few days. "The EPCA is part of a concerted international effort to provide assistance to Lebanon," Khan said, referring to $7.6 billion in aid and loan pledges won by the country at a January Paris donors conference after the 34-day war last July. None of the money pledged in Paris has yet been paid to Lebanon and some of the donors, including the European Commission and World Bank, actually require the involvement of the IMF before they can hand over any funds. As a result, Monday's news removes an important obstacle to the payment of some of the Paris money, which Lebanon is counting on to stay on track with an ambitious 5-year reform program. "The authority's financing strategy for this year relies on the timely disbursement of donor support, which they have been promised, and that is going to be very important in limiting the further buildup of government debt," Khan said. The government of pro-western Prime Minister Fouad Siniora aims to trim back Lebanon's hefty public debts. These stand at $40 billion, representing 180 percent of the country's gross domestic product, and the intention is to lower this to 130 percent of GDP over five years, using a mixture of government spending measures and privatization. "2007 is shaping up to be a difficult transition year and in the EPCA they commit themselves to containing the fiscal deficit, while still at the same time allowing for relief and reconstruction spending," Khan said. Acknowledging that the volatile regional political climate exposes the country to swings in investor confidence, Khan said that it would continue to manage its currency. "The Lebanese authorities remain committed to foreign exchange stability and this means they will maintain the exchange rate peg," he said. Khan said that he expected the emergency loan to lead to a full standby credit arrangement with the IMF next year, although size and loan conditions still had to be worked out.
