Russia's Defense Minister Sergei Shoigu will visit Tehran on September 19, Iran's semiofficial Tasnim news agency reported, adding that he would meet top Iranian officials. Since the imposition of Western sanctions on Russia following its invasion of Ukraine in February 2022, Tehran and Moscow have deepened their bilateral ties, notably in the military sphere. Last month, Russian Deputy Foreign Minister Sergei Ryabkov said Russia's military cooperation with Iran would not succumb to geopolitical pressure, following a report that Washington had asked Tehran to stop selling drones to Moscow.
