US President Joe Biden told EU leaders he’s concerned about Turkey’s democratic backsliding and Ankara’s closer ties with Russia, according to several EU officials with knowledge of the exchange, Bloomberg reported.

The US president’s comments come after a turbulent week for Turkey’s markets, following the abrupt sacking of the country’s central banker.

During their video call, EU leaders upheld the threat of sanctions against Turkey, while promising closer economic ties if Ankara stands down from its claims over natural gas reserves in the Eastern Mediterranean.
