Western governments are increasingly alarmed about deepening economic ties between Turkey and Russia, warning of the mounting risk that Turkey could be hit by punitive retaliation if it helps Russia avoid sanctions, the Financial Times reported on Saturday.

Six Western officials told FT that they were concerned about the agreement.
