MSOCOW--Russia's industrial production growth slowed in January, falling below the 2014 average, data from the federal statistic service RosStat showed Monday.

The data showed industrial production grew 0.9% in January from the same month of 2014. In December the growth rate was 3.9%, while for the whole of 2014 industrial production was up by 1.7%.

In monthly seasonally-adjusted terms, industrial production fell 1.8% from the previous month.

Russia's economy is heading towards its deepest contraction in six years in 2015, as the combination of weaker oil prices and Western sanctions imposed for the Kremlin's policy in Ukraine have hit the ruble and fueled both inflation and capital outflows.

The January figures show the deepest contraction in manufacturing sectors connected with construction.

However, Russia increased its food production, as retailers replace Western food, the import of which the Kremlin banned in August, with domestic produce. Meat production was up by 20.9%, cheese output was up by 35.1%, and canned vegetable production increased by 47%.

Prior to August, Russia imported about a third of the food it needed. The imposed embargo and the weakening ruble have given a boost to the food processing and agriculture industry, historically a backwater of the Russian economy.
