"The head of the First Eastern Europe Department at the Iranian Foreign Ministry told the Polish charge d'affaires that the upcoming conference was a hostile move by the United States against the Islamic Republic of Iran and that Poland was expected to refrain from cooperating with the United States on holding this conference", the statement, published on the ministry's official website, said, adding that the diplomat had been summoned "in protest against the anti-Iran conference".
According to the statement, the Polish diplomat, for his part, said that the summit’s agenda was not anti-Iranian and that Warsaw's stance on the issue was different from recent statements made by US officials.
