"Ireland is a member of the European Union and because EUs stances on peace-seeking issues are closer to reality, I explained the nuclear issues for the Irish speaker," Larijani said, addressing a joint press conference with his Irish counterpart in Tehran on Tuesday.
He expressed the hope that the visit of the Irish parliament speaker and his meetings with senior Iranian officials would result in the further expansion of the two countries relations.
Larijani told reporters that during his meeting with Barret, they discussed important issues, specially combatting terrorism.
Barret, for his part, pointed to the status quo of Iran-Ireland relations, and said, "I had good negotiations with Dr. Larijani on nuclear issues."
The speaker of the Irish Lower House of Parliament arrived in Tehran on Tuesday to discuss bilateral ties with senior Iranian officials.

The population of Ireland is approximately 6.4 million.
On Saturday, Iranian and Irish parliamentarians explored new avenues for widening and deepening of Tehran-Dublin ties.
In a meeting between Iranian delegation headed by Chairman of Iran-Ireland Parliamentary Friendship Group Javad Heravi and Chairman of the Oireachtas (Irish National Parliament) Foreign Affairs and Trade Committee Pat Breen in Dublin, the two sides underlined the impotence of expanding parliamentary relations as a base for enhancement of all-out relations.
Heravi, in the meeting, underscored that the cooperation among the global and regional countries would play a pivotal role in preventing the spread of terrorism as well as narcotic-trafficking.
Ireland has always been recognized as a peace-lover and neutral county in the international equation, he added.
Breen, for his part, underscored that the Islamic Republic of Iran plays a vital role in regional equations.
With several thousand years of civilization, Iran could help establish peace and tranquility in the entire region, he added.
Iran, on many occasions, has stressed that expansion of ties with friendly states stands atop its foreign policys agenda.
