Türkiye has blocked supplies of Western goods to Russia that could be used for military production.
Ankara was forced to take this step after the US warned about possible consequences.
The Turkish government has not officially announced the restrictions, the Financial Times reports, citing sources.
Türkiye has banned the export of more than 40 categories of American-made goods to Russia.
Turkey's electronic customs system no longer allows the export of military goods to Russia.
The ban primarily affected the supply of microchips and remote control systems for the production of weapons systems.
