Kremlin claims Vladimir Putin has restricted hiring of Turkish staff in Russian companies

Russian President Vladimir Putin signed a decree imposing economic sanctions against Turkey on Saturday, four days after Turkey shot down a Russian warplane near the Syrian-Turkish border.

The Kremlin website said the measures would affect imports of some Turkish products, operations of Turkish companies in Russia, and employment of Turkish staff by Russian firms.

The website also claims that Putin has ordered some Russian companies to restrict hiring of Turkish staff starting January 1. 

On Saturday, Kremlin also said that Putin is fully mobilised to tackle what the Kremlin regards as an unprecedented threat from Turkey following the shooting down of one of its warplanes by a Turkish F-16.

In comments which underscore how angry the Kremlin still is over the incident, Dmitry Peskov, Putin's spokesman, called the behaviour of the Turkish air force "absolute madness" and said Ankara's subsequent handling of the crisis had reminded him of the "theatre of the absurd."
