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.
