Turkey, Armenia’s historic enemy with whom it shares its largest border, is also an ally of Azerbaijan. Turkey and Azerbaijan have long refused to allow any Armenian trade over their air or land space. Lacking a sizeable enough border with Iran to facilitate major trade means Armenia is effectively dependent on the Georgia and Iran to conduct international trade. In order to avoid disturbing relations with Azerbaijan, Georgia imposes certain limits on Armenian imports.

Qatar was also criticized for its close relations with Iran and the management of Al Jazeera.

1989	Armenia	Azerbaijan Turkey	Nagorno-Karabakh conflict & Pan-Turkism	Main article: Turkish–Azeri blockade of Armenia (1989–ongoing) The blockade was initiated in 1989 by Azerbaijan, originally in response to the Karabakh movement which called for independence from Azerbaijan and reunification with Armenia.
