President Hassan Rouhani voiced Iran's willingness to foster broader cooperation with the European Union, especially against terrorism.
The president made the statement in a meeting with Estonian Foreign Minister Marina Kaljurand in Tehran on Sunday, IRNA reported.
Rouhani stressed the need for the contribution of all countries in the fight against terrorists who are destabilizing some countries in Africa and Asia.
"The Islamic Republic of Iran is concerned over instabilities in some countries in the Middle East and North Africa," he said.
"Making efforts to establish security in these countries will help improve stability in the entire region and the world."
Rouhani warned that if no "real fight" is mounted against terrorism, experience shows that the scourge may spread to other regions, including Europe.
The president added that Iran and the EU can also work to help settle "complicated regional and international problems" to help promote peace.
On bilateral ties with Estonia, Rouhani said Tehran and Tallinn enjoy huge potentials to deepen cooperation, which needs to be tapped.
Kaljurand said Estonia seeks to develop partnership with Tehran in all fields of mutual interest.
"Increasing cooperation is to the benefit of the two nations," she said. "We are committed to developing ties between the two countries."
Also on the same day, the Estonian foreign minister met her Iranian counterpart, Mohammad Javad Zarif, following which the two officials held a joint press conference.
Zarif noted in the conference that the two countries are able to engage in political, parliamentary, cultural, scientific and economic cooperation.
Kaljurand described her discussions with Iranian officials as "very good" and hoped for promoting cooperation between Tehran and the Baltic country.
Heading a high-ranking politico-economic delegation, Kaljurand arrived in Tehran on Sunday for a two-day visit, aiming to expand mutual ties and review the latest international developments.
The visit comes against a backdrop of global enthusiasm for closer ties with Iran after the removal of international sanctions on the country as a result of its nuclear deal with major powers.
