 But at least some of these issues have been largely resolved, says Sinan Ulgan, a former Turkish diplomat and the director of the EDAM think tank.

This week at the NATO summit, leaders will discuss military support for Ukraine, a goal that Ulgan says Turkey agrees with. But the country has maintained deep economic ties to Russia since the invasion began.
