Russian President Vladimir Putin signed a decree Nov. 28 with immediate effect imposing sanctions against Turkey for the downing of a Russian Su-24 on Nov. 24, Reuters reported citing a statement posted on the Kremlin's website. The sanctions will ban charter flights from Turkey and prevent Russian tour companies from selling packages for travel the country. It will also entail the halt of unspecified Turkish imports while limiting the economic activity of certain Turkish corporations and individuals. The Russian government will publish the full list of specific goods and firms Nov. 30, with foodstuffs likely to be included according to unnamed officials, Interfax reported. Putin has voiced concern that Turkish President Recep Tayyip Erdogan has not issued an apology for the incident, while Erdogan has insisted Turkey will not apologize. Erdogan has requested to meet with Putin on the sidelines of a U.N. climate change summit that will begin Nov. 30 in Paris. Trade between Russia and Turkey is heavily concentrated in a handful of sectors, the most important of which are energy, metals and agriculture. Altogether, Russian exports make up about 10 percent of Turkey's imports, while Turkey accounts for only 4 percent of Russia's exports.
