Greece doubled its forecast for a budget surplus before interest payments this year, boosted by better than expected tax revenues, a revised budget plan for 2014 showed on Thursday.
Athens also confirmed its economy would return to growth next year after a six-year recession, posting growth of 0.6 percent.
Posting a primary surplus makes Athens eligible for debt relief from international lenders that have bailed out the country twice since 2010.
Athens will report a primary budget surplus of at least 712 million euros this year, compared to a previous forecast of 344 million euros made in a draft budget plan last month, Staikouras said.
Greece maintained its forecast for a primary surplus of 1.6 percent of gross domestic product next year.
