(Reuters) – Sri Lanka aims to announce a debt-restructuring strategy in April and step up talks with commercial creditors ahead of an International Monetary Fund review of a bailout package in six months, the nation's central bank governor told Reuters.The crisis-hit island has secured financing assurances from all its major bilateral creditors, including India and China, and so has set the stage for the IMF to give its final approval for a $2.9 billion, four-year bailout package on March 20, the multilateral lender said on Tuesday.The bailout is the culmination of months of negotiations as Sri Lanka looks to emerge from its worst economic crisis in more than seven decades."When you see the staff level agreement published – that will contain our commitment to debt restructuring and that will also reveal medium-term debt targets for us to restore debt sustainability on a long-term basis," central bank Governor P. Nandalal Weerasinghe said on Thursday."So somewhere in April we will announce … how we are going to meet those medium-to-long-term (debt) targets.
