Nicaraguan parliament speaker is scheduled to arrive in Tehran on Sunday to meet with senior Iranian officials on bilateral ties.The visit by the Nicaraguan speaker and his accompanying parliamentary delegation will take place at the invitation of Iranian parliament Speaker Ali Larijani.During the visit to Tehran, the Nicaraguan delegation will hold meetings with Larijani, President Mahmoud Ahmadinejad, Iranian Foreign Minister Ali Akbar Salehi and Chairman of the parliament\'s National Security and Foreign Policy Commission Alaeddin Boroujerdi as well as the members of Iran-Nicaragua parliamentary friendship group.The delegation also plans to pay a visit to Iran\'s historical city of Isfahan.Iran has been seeking to boost its ties with Latin American countries in recent years to the concern of the United States.Since taking office in 2005, President Ahmadinejad has expanded Iran\'s cooperation with many Latin American states, including Venezuela, Bolivia, Cuba, Ecuador, Nicaragua and Brazil.The strong and rapidly growing ties between Iran and Latin America have raised eyebrows in the US and its western allies since Tehran and Latin nations have forged an alliance against the imperialist and colonialist powers and are striving hard to reinvigorate their relations with the other independent countries which pursue a line of policy independent from the US.
