The original decree signed by President Vladimir Putin declared the embargo would last for one year, but it has since been prolonged in step with EU/US sanctions.
Last month, the EU Council extended anti-Russian sanctions until January 31 2017, and Russia extended its counter-sanctions until December 31 2017.
The counter-sanctions have had a negative impact on Western food producers: European farmers in particular have lobbied their governments to lift sanctions against Russia.
At the end of July, the regional parliament in Piedmont made it the fifth Italian region to approve a resolution calling for anti-Russian sanctions to be lifted, under pressure from local farmers.
In addition to this political aspect, the Russian counter-sanctions were intended to stimulate Russia's agricultural production, which constitutes around four percent of Russia's GDP.
Last year Russia's agricultural industry recorded annual growth of 3 percent, and grew by another 2.6 percent (annualized) in the first half of 2016.
In May 2014, the Russian President approved a raft of measures to stimulate growth across the economy, including tax breaks to stimulate private investment in industry, state investment in road-building, and state support for industrial projects which practice import substitution.
The Industrial Development Fund was set up to provide loans to companies seeking to modernize their equipment, or substitute products which are currently imported.
In 2015 the fund provided 20 billion rubles ($305 million) in credit, and so far this year it has approved 23.7 billion rubles ($362 million). Much of the financing has gone to machine-building projects (7.3 billion rubles), or funding for companies producing medical or pharmaceutical products (4.17 billion rubles).
In October 2014 the Russian government approved a two-year "road map" on import substitution for Russia's agricultural sector, which included developments in infrastructure and logistics, and the regulation of customs tariffs.
On Friday Tatyana Radchenko, deputy head of the Russian government's Analytical Center told RIA Novosti that during 2014 and 2015, Russia's production of meat and poultry rose by an average of ten percent, the production of cheese products rose by 10.6 percent and butter by 3.2 percent.
Radchenko said that the proportion of imported meat and poultry products on the Russian market decreased from 27 percent in 2013 to 13 percent in 2015. The proportion of imported butter decreased from 36 percent to 26 percent, and imported cheese from 48 percent to 23 percent.
The analyst sought to allay fears that such success might be undone, if the sanctions were to end.
"Firstly, Russian consumers have switched to domestic and Belorussian brands, which have strengthened their share of the food market. Secondly, retailers have agreed on contracts with new suppliers for products," Radchenko said.
"Switching back to the previous foreign suppliers will only be possible if they propose lower prices, which is hardly possible with the current exchange rate."
"It seems unlikely that there will be a crisis of overproduction in countries under the embargo, which would lead producers to significantly decrease their prices," Radchenko said.
Russia's increase in food production has not only benefited domestic consumers; according to Russia's deputy minister for economic development Aleksey Likhachev, Russia's agricultural exports in 2016 "demonstrated fantastic results."
He told the St. Petersburg economic forum in June that the volume of Russia's food exports increased by 30.5 percent in the first four months of 2016, and that agricultural industry exports increased by five percent in dollar terms.
"The main partners were machine-building companies, producers of energy and transport machinery, petrochemicals, metallurgy and I would like to particularly emphasize, agriculture," Likhachev said.
In July the President approved a law banning the production of genetically modified crops or animals in Russia, but Radchenko's Analytical Center thinks the law, which goes into force in July 2017, might have to be looked at again.
"In the context of increasing food exports to countries where the food production is carried out under different conditions than in Russia, we suggest raising the question of allowing genetically modified crops in agriculture. This could partially reduce costs and increase the competitiveness of Russian food products abroad," Radchenko said.
