Iran is ready to make more agreements with other countries about the exchange of prisoners.
Iranian Deputy Foreign Minister Abbas Araghchi on Friday calls it “a legitimate resource that matches our national interests”.
Other countries have released nine Iranians in recent months in exchange for the return of six people detained in Iran. The last exchange was this week. Three Iranians detained in Thailand have been released in exchange for Australian-British academic Kylie Moore-Gilbert.
She arrived in Australia on Friday after spending more than 800 days in jail on suspicion of espionage.
Aragchi did not say on Friday whether Iran will also release people with an Iranian and a foreign passport.
Many people with double passports are stuck in the country, often on suspicion of espionage. Iran does not recognize dual nationalities; the nationality of the father is valid in the country.
