The figure is well below the IMF's previous estimate of 2.7% and would be only slightly higher than economic growth in 2013, which stood at 1.9%.
The IMF pointed to recent data showing a "meaningful rebound" in activity, adding that it will only partly offset a contraction that occurred in the first quarter.
The factors underpinning the economic slowdown include an ageing population as well as high levels of poverty and long-term unemployment, the IMF said.
