Pakistani President Asif Ali Zardari is scheduled to pay a two-day visit to Iran on June 23, Fars News Agency reported.
During his stay in Tehran, the Pakistani president will attend an international conference on campaign against terrorism and hold meetings with senior Iranian officials, including President Mahmoud Ahmadinejad, to discuss a vast range of issues including regional security situation.
The International Conference on Campaign against Terrorism is due to be held in Tehran from June 22 to 23 with officials of more than 80 countries as well as regional and international organizations in attendance.
Iranian Foreign Ministry Spokesman Ramin Mehman-Parast had earlier said that in addition to the officials of different countries, a number of presidents of the world states have also been invited as special guests of the conference.
He also reiterated that the Islamic Republic of Iran as one of the biggest victims of terrorism is determined to annihilate the ominous phenomenon through cooperation with other countries.
Iran last month had hosted an international conference dubbed 'International Coalition against Terrorism for Fair Peace' with more than 1,000 Iranian and foreign figures and thinkers in attendance.
The gathering mainly sought creation of mutual understanding, wise thinking and fair and just international efforts to annihilate terrorism.
Also four specialized meetings with the topic of terrorism were held on the sidelines of the conference.
Iran along with many other Muslim countries have criticized the western countries' selective approach towards terrorism, specially after the September 11 attacks in the US.
Earlier, Iran's Deputy Ambassador to the United Nations Eshaq Ale-Habib lambasted the world powers' double-standard approach to terrorism, stressing that such policies have caused a further spread of terrorism in the world.
Addressing the annual meeting of the UN Security Council's Counter-Terrorism Committee, Ale-Habib said that certain western powers continue to take advantage of terrorist activities and groups to accomplish their political objectives and increase pressure on the other countries.
"Unfortunately, these countries do not doubt to negotiate and cooperate with terrorists whenever beneficial to them," he added.
