Moscow imposed a total ban on imports of many Western foods on Thursday in retaliation against sanctions over Ukraine, a stronger than expected measure that isolates Russian consumers from world trade to a degree unseen since Soviet days.
In eastern Ukraine, a Dutch recovery team called off its work at the site where Malaysian airliner MH 17 was shot down over rebel held territory last month, saying the frontline location had become too dangerous.
Ukraine said the halt to the recovery meant it would stop observing a ceasefire at the site, where it is battling rebels that the West says are armed and funded by Moscow.
Russian share prices fell after the announcement of Moscow's one year ban on all meat, fish, dairy, fruit and vegetables from the United States, the 28 European Union countries, Canada, Australia and non-EU member Norway.
Russia bought $43 billion worth of food last year. It has become by far the biggest consumer of EU fruit and vegetables, the second biggest buyer of U.S. poultry and a major global consumer of fish, meat and dairy.
President Vladimir Putin ordered his government to adopt the measures to retaliate against Western countries who imposed sanctions on Russia's defense, oil and financial sectors over its support for rebels waging an insurrection in east Ukraine.
He had promised to ensure that the measures would not hurt Russian consumers, which suggested he might exclude some popular products. But in the end, the bans announced by his prime minister, Dmitry Medvedev, mentioned no exceptions.
The announcement saw Russian bond yields rise to their highest levels in years and Moscow's already reeling share prices extend a sell-off.
Agriculture Minister Nikolai Fyodorov acknowledged that the measures would cause a short-term spike in inflation, but said he did not see a danger in the medium or long term. He said Russia would compensate with more imports of products from other suppliers such as Brazilian meat and New Zealand cheese.
The EU's executive Commission said it reserved the right to take action to retaliate against the Russian ban.
Farmers in specific sectors in Western producing countries are likely to suffer, but much of the pain will be borne by Russians, who will face higher prices and shortages of some goods, with inflation already rising, the rouble falling and the economy hurt by capital flight.
"The first casualties would be the domestic market. However it will have some implications for the farmers in the producing countries," Abdolreza Abbassian, a senior economist with the United Nations Food and Agriculture Organization, said.
