MOSCOW — Turkish soccer players are off-limits. Ottoman-Turkish language classes are canceled. Frozen turkey parts from Turkey have been banned.

When Russian Prime Minister Dmitri Medvedev ordered his government last week to draft economic sanctions against Turkey, no ministry was left out. Some of the sanctions in the wake of Turkey's downing of a Russian warplane over the Syrian border and the deaths of two Russian servicemen will have serious consequences. Others, as one commentator noted, seemed puerile.

Not all of Russia's anti-Turkish sanctions have been announced yet, but the major targets will be in the tourism, agriculture and business sectors. Russia has already banned the sale of all-inclusive tour packages and charter flights to Turkey and announced a freeze on imports of tomatoes and other foods from Turkey. Turkish construction workers have been arrested over purported visa violations, and licenses for Turkish cargo trucks will be cut by three-fourths.

Then there are more baffling moves, such as the closure of the Russian-Turkish research center at Moscow's Library for Foreign Literature on Tuesday.

"The Russian-Turkish Research Center at the Library of Foreign Literature no longer exists," the center wrote in a statement on Tuesday. "Language courses in Ottoman Turkish will cease. We can no longer provide assistance to graduate students. Naturally, all the planned roundtables, lectures and conferences are canceled."

"We don't know the reasons for the closure," the statement said.

Russia is hoping to make good on its threats that last week's plane incident — which President Vladimir Putin deemed a "stab in the back" — will have "serious consequences." That has meant everything from ending Turkey's visa-free relations with Russia to cutting cultural ties between Russian regions with large Turkic populations and Ankara.

The research center was not the only academic partnership targeted Tuesday. Russia's Education Ministry said it would immediately repatriate every Russian studying in Turkey. Overall, 44 Russian universities said they had canceled academic partnerships with Turkish institutions.

The crackdown also included sports. Russian Sports Minister Vitaly Mutko said Tuesday that athletes and soccer clubs would no longer train in Turkey during the winter.

Mutko told the state-owned news agency R-Sport that he had directed soccer clubs not to hire Turkish players during the upcoming winter transfer period. Turkish players already on the roster can remain, he added.

One of the main elements of the sanctions fell into place Tuesday evening, as the Russian government announced it would ban the import from Turkey of frozen turkey and chicken parts, cloves, tomatoes, onions, broccoli, cabbage, oranges, mandarins, grapes, apples, pears, apricots, peaches, salt and more. Turkey imported $281.3 million in tomatoes in 2014, 9.1 percent of its total exports to Russia. Exports of citrus fruits to Russia were worth $134.9 million, constituting 4.4 percent of Turkish exports to Russia, but that includes fruits such as lemons, which are not on the list.

Those sanctions are expected to cause serious headaches for Turkish exporters and for Russian supermarket chains, which will have to find new sources of fruits and vegetables — perhaps as far away as Argentina or South Africa. Russia has often closed its markets to food imports in a bid to apply political pressure, and the food sanctions against Turkey resemble those imposed against the West last summer, culminating in the public destruction of banned foods.
