Economy Minister Alexei Ulyukayev said that Russia's economy grew just 0.8 per cent in the first quarter of 2014, compared to activity in the same period last year.
But it contracted 0.5 per cent versus the final three months of 2013, after seasonal adjustment, Russian news agencies quoted Ulyukayev as telling parliament.
A recession is defined as two consecutive quarters of shrinking economic output. Many analysts believe Russia will fall into recession owing to the impact of the Ukraine crisis.
"The economic situation has become even more strained and internal factors have been exacerbated by a high level of uncertainty on currency and financial markets, serious capital flight, an unreadiness by investors to take decisions in this acute international situation, which has taken shape in the last two months," he said.

Finance Minister Anton Siluanov yesterday warned that Russia economy could be set back to zero growth this year as it faces "the most difficult conditions since the 2008 crisis," when it went into deep recession.
"Over the past seven months nothing comforting happened and the situation in fact became even more tense than before," he added.
He said that Russia was now experiencing a "pause in investment" with volumes down 4.8 per cent in the first quarter from the same period a year earlier.
"The latest economic data indicate that the tentative economic recovery at the end of last year started to fizzle out, even before the crisis in Ukraine escalated," said economists at Capital Economics in a note to clients.
The outflow of capital has also pushed down Russia's ruble, which in turn has aggravated Russia's inflation problem. The headline rate rose to 6.9 per cent last month, Capital Economics said.
