Bahram Qasemi made the remarks Monday in a press conference.
In response to a question on Pakistan FM's trip to Iran and whether both sides would hold talks on the new strategy adopted by the US on Afghanistan, Qasemi said the meeting aims at discussing issues of mutual interest, and also regional affairs.
He urged all neighboring countries to spare no effort to create peace and stability in Afghanistan.
Those who are interested in Afghanistan should reduce their interference in this country, Qasemi said.
