Russia bans Turkish food imports (2015-2016)
Turkey shot down a Russian Su-24 bomber near the Syrian border in November 2015. Moscow responded with sanctions, including a ban on Turkish agricultural imports that hit exporters in both countries.
Trade collapsed and tourism fell; Ankara apologized in mid-2016.
Russia lifted most restrictions within months of the apology, and the episode became a template for using trade bans as leverage in security disputes.
Sudan's tea ban followed the same pattern: a political grievance translated into a commercial cutoff, resolved once the underlying dispute was addressed through back-channels.
