Tehran and Astana have signed 66 memorandums of understanding and agreements worth $2 billion in various arenas, including economy, commerce, agriculture, industries and mining.
Kazakhstan's President Nursultan Nazarbayev made the announcement in a joint press conference with President Hassan Rouhani in Tehran on Monday, according to President.ir.
In the meeting of high-ranking delegations of the two countries headed by their presidents, which was held before the press conference, nine agreements were signed in the fields of commerce, banking, investment, industries, railroads and shipping, among others.
Nazarbayev said in the press conference that the removal of international sanctions on Iran as a result of its nuclear deal with major powers has opened a "new chapter" in relations between Tehran and Astana.
"There are lots of capacities for increasing cooperation between the two countries," he said. "We are committed to activate these capacities."
The Kazakh president said his country and Iran hold common stances on many regional issues.
To deal with the threat of terrorism, Nazarbayev stressed the need for promoting Muslim unity.
"We should divide terrorism and Islam and fight terrorism in a united manner," he said.
Rouhani described the trip as a "milestone" in relations of the two sides and said Tehran welcomes enhanced ties with Astana in political, economic and cultural areas.
To develop economic cooperation, the Iranian president said governments should support private sectors for establishing contacts and working with each other.
Rouhani said the two Asian countries believe extremism, terrorism and sectarian strife are major dangers threatening the Muslim world.
The president said the latest developments in Afghanistan, Iraq, Syria and Yemen were reviewed by the two sides, which agree that only a political approach could help solve problems in the Muslim countries. Heading a politico-economic delegation, Nazarbayev arrived in Tehran on Monday for a two-day stay.
The visit to Tehran comes at the invitation of the Iranian president and in response to an earlier trip by Rouhani to Astana on September 8-9, 2014.
