The Sassanids undertook to evacuate Lazica, but the status of the neighboring country of Suania was left unclear to become a future source of disagreement. The Sassanids were to receive an annual subsidy of 30,000 gold nomismata, with the first seven years payable immediately.[1] The expenses of the defense lines in the Caucasus against the nomads in the north, for which there was a mutual interest and had been the responsibility of the Sasanians, were included in the payments.[2] Both sides agreed not to establish new fortifications or fortify the existing settlements on the border. To prevent spying, trade was restricted to Callinicum, Nisibis, and Dvin, while traders from other nations were restricted to Dara (under the Byzantines) and Nisibis (under the Sasanians).
