Fitch Ratings has affirmed France's sovereign debt rating at 'AA+' on Friday. The outlook is stable.

"France's ratings balance a wealthy and diversified economy, track record of relative macro-financial stability, strong and effective civil and social institutions with a high general government debt/GDP ratio and fiscal deficit," Fitch said in its statement.

The agency expects the French economy to expand 1.1% in 2015, 1.5% in 2016 and 2017.

"France's economic recovery is proceeding with growth this year supported by low oil prices and favourable monetary and tax policies boosting private consumption, and the euro depreciation bolstering exports," the agency noted.

Inflation is expected to climb from 0.1% this year to 1.3% by 2017, while unemployment rate is expected to be 10.5% in 2015, falling to just below 10% by 2017.

Fitch expects France's government deficit to decline to 3.4% of GDP in 2016 and 2.8% in 2017 from 3.8% in 2015.
