Russia considers limiting exports of vital goods while softening imports as part of the government’s response to the global coronavirus crisis.

Prime Minister Mikhail Mishustin has ordered officials to report by Wednesday whether there should be restrictions on exports of food, medicine, and other essential consumer goods. The instructions follow other measures in recent days to prevent potential contagion effects, including a “green corridor” for some imported goods.

Russia is the largest producer of wheat in the world, and its other agricultural commodities sales are mostly sunflower oil and fish. Mikhail Mishustin said last Thursday that the country had enough food, but an ordinance published today said the government should reconsider domestic supplies every week. Wheat prices in Russia and the world have skyrocketed in recent days as people stock up.

“With this rapid increase in prices, the risks of curtailing wheat exports have increased dramatically. Price rises have not stopped yet:, said Andrey Sizov Jr, managing director at consulting firm SovEcon.

Closing the door on exports of some foods could neutralize Russia’s progress in reaching new markets such as China, according to the Association of Food Producers and Suppliers. Manufacturers make sure employees stay home if they are not feeling well, and many companies are at a lower risk of being shut down because of the high level of automation, says Dmitry Vostokov, director of the development department at the association.

One measure to ensure that Russians are well stocked with consumer goods was approved last week. By Friday, the government eased the rules on imports of certain products by one month and reduced the import duties on medicines to zero.

Earlier today, Russia identified McDonald’s as a systemically important company, and the government tripled the number of those companies in an attempt to avert a possible recession. Ikea and Auchan Holding are among other foreign companies considered vital to the economy after a government commission expanded the list to 600 companies to 200 so far.

Russia is trying to strengthen the position of some of its biggest employers and essential services after the economy was shaken by the double shock of the coronavirus and the collapse in oil prices. Black gold has become cheaper because of declining demand and the price war between Russia and Saudi Arabia, which has led the ruble down 23% since the beginning of the year.

McDonald’s, which opened its first facility in Moscow in 1990, has often been attacked by Russian populist politicians. But the company is one of the leading operators of fast-food establishments in the country and operates more than 800 restaurants in Russia.

Systemically important companies will be subject to stress tests from next week and may receive additional government support. Other companies included in the list are airlines and grocery stores, Vedomosti reports.

The government has allocated 300 billion rubles (3.7 billion USD) to offset the effects of the epidemic. Russia, which has stopped most foreigners from entering and closed schools this week, is considering stricter measures to curb the spread of the disease.
