Kuwaiti ambassador to Iran Majdi Az-Zoheiri will return to Iran on Tuesday, May 24, IRNA reported.
Al-Zoheiri has been the Kuwaiti ambassador to Iran since 2001. He was recalled from Tehran in March 2011after spying dispute between Iran and Kuwait.
Iranian ambassador to Kuwait Rouhollah Ghahramani Chabok arrived in El-Kuwait Monday morning.
On Monday, Iranian Foreign Ministry Spokesman Ramin Mehmanparast said Iran and Kuwait would resume ambassadors' mission this week.
Iran said ambassadors of the two countries would return to their posts soon.
The measure came after a Kuwaiti criminal court in March accused two Iranian and one Kuwaiti individuals of espionage for Iran's Islamic Revolutionary Guards Corps (IRGC).
Iranian President Mahmoud Ahmadinejad rebuffed such accusations and said Iran was not operating spy ring in Kuwait.
Kuwait later recalled its ambassador to Tehran and expelled several Iranian diplomats following accusation of their involvement in the spy ring.
Iran expelled some Kuwaiti diplomats in retaliation.
Also Iranian Foreign Minister Ali Akbar Salehi has recently visited Kuwait and held talks with officials of the country.
