Russian Prime Minister Dmitry Medvedev ordered the Russian government to draw up measures that would include freezing some joint investment projects with Turkey, in retaliation for the downing of a Russian warplane by Turkey, RIA Novosti news agency reported.
He also told a meeting of cabinet ministers on Nov. 26 that the measures would include restrictions on food imports from Turkey.
The Turkish Air Force shot down the Russian military plane SU-24 in its airspace Nov. 24.
Both pilots managed to eject and the plane crashed on the territory of Syria. Relations between Russia and Turkey have deteriorated after this incident.
