NATO leaders must clearly and unequivocally commit to values ​​and rules at next month's summit, French President Emmanuel Macron said, subtly hinting at Turkey’s behavior within the alliance, AP reported.

Speaking to reporters in Paris alongside NATO Secretary-General Jens Stoltenberg, Macron said leaders, including US President Joe Biden, should openly discuss cohesion within NATO at a June 14 summit in Brussels. 

According to him, it is important for countries not to focus on national interests that contradict the security of other allies, as it has been in recent years in Syria, the Eastern Mediterranean, Libya, and the Caucasus. He also noted interoperability of weapons, which is absolutely essential for NATO.

The French president did not name Turkey, but the latter has been criticized for its exploration activities in the Eastern Mediterranean. Last year, Turkish warships also prevented a French frigate from inspecting a freighter bound for Libya.

As a result of Turkey's purchase of Russian S-400 systems, which NATO says could threaten its own defenses, the United States has excluded the country from its F-35 stealth fighter program.

All Stoltenberg said was that the leaders will strengthen our unity and solidarity in the future.

This means more consultation within NATO on all issues affecting our security, reaffirming our fundamental values ​​and strengthening our commitment to collective defense, including through increased investment, he said.
