These joint activities are planned to start as soon as possible," Yilmaz said, according to the official translation.He also mentioned his country's involvement amid the ongoing Russian aggression against Ukraine."Since the beginning of the war in Ukraine, Turkey has fought very hard to stop the war, to ensure basic global security, for the safety of navigation in the Black Sea and we will continue to work in that area, thanks to the Black Sea Straits Convention, under which we have to ensure security in the area, lower the tension in the area and ensure the security of our area," Yilmaz said.At the same time, Turkey's vice-president spoke about the regional security situation.
