Turkish-Russian relations are entering a new stage as they prepare to start joint patrols of a strip 10 kilometers (six miles) deep inside northeastern Syria Friday following Ankara’s incursion into the region this month to expel US-backed Kurdish forces.
As the two nations coordinate operations on the ground, negotiations are taking place between state officials over Ankara’s possible purchase of Russian-made Su-35 warplanes. Turkish President Recep Erdogan expressed interest in the jets following Turkey’s acquisition of Russian S-400 missile defense systems in July, which riled long-time NATO allies and may result with sanctions for violating regulations meant to deter purchases of Russian military technology.
