ISTANBUL: Turkey's top business association has confirmed receiving a letter from the US Treasury warning of possible sanctions if it continues doing business with Russia, reports AFP.
Washington is growing increasingly alarmed that the Russian government and businesses are using Turkey to evade Western financial and trading restrictions imposed in response to the Kremlin's invasion of Ukraine six months ago.
Official data show the value of Turkish exports to Russia between May and July growing by nearly 50 percent from last year's figure.
Turkey's imports of Russian oil are ballooning and the two sides have agreed to transition to ruble payments for the natural gas exported by the Kremlin-tied giant Gazprom.
US Deputy Secretary of the Treasury Wally Adeyemo paid a rare visit to Ankara and Istanbul in June to express Washington's worries that Russian oligarchs and big businesses were using Turkish entities to avoid Western sanctions.
