Turkish Aselsan and Ukraine's Ukroboronprom are exploring ways to undertake joint programs designed to upgrade tanks.
The cooperation will later expand into upgrading artillery and personnel carriers, one Aselsan official said.
The Turkish-Ukrainian talks came at a time when Russia, Turkey's top trade partner and main natural gas supplier, became both countries' foe.
Russian President Vladimir Putin said the sanctions on Turkey will not be economic and commercial only.
Military electronics specialist Aselsan announced Nov. 30 that it signed a contract with the Turkish government to produce and deliver an indigenous system designed to protect tanks and armored vehicles from anti-tank rockets and missiles.
Aselsan said the AKKOR is designed to detect rockets and missiles targeting tanks and hit them while in the air.
The Aselsan official said that the cooperation with Ukroboronprom may also involve further refining and fine-tuning the AKKOR.
