A Foreign Ministry official told Poland's Charge d'Affaires in Tehran Wojciech Unolt that Iran saw the decision to host the meeting as a "hostile act against Iran" and warned that Tehran could reciprocate, IRNA reported.
"Poland's charge d'affaires provided explanations about the conference and said it was not anti-Iran," a Foreign Ministry statement said.
The statement quoted the unnamed official as saying that if the summit goes ahead, Iran will resort to unspecified "counteraction" toward Poland, without elaborating.
Separately, Iran's Culture Ministry in a statement said it was suspending "Poland's Film Week," supposed to be held in Tehran in late January, until Warsaw mends its ways and starts applying "appropriate behavior" toward Tehran.
"Iranians have hosted various nations and ethnic groups with open arms, especially the Poles," Hossein Entezami, the head of the Cinema Organization of Iran, said on Twitter. "In order to protect the honor of Iran and Iranians, the holding of the Polish Film Week will depend on Warsaw's appropriate behavior."
US Secretary of State Mike Pompeo said on Friday the summit – to be held in Warsaw on Feb. 13-14 – would focus on stability and security in the Middle East, including on the "important element of making sure that Iran is not a destabilizing influence".
Relations between Tehran and Washington are highly fraught following the decision in May by US President Donald Trump to withdraw from a 2015 nuclear deal between Iran and world powers and to reimpose sanctions, including on Iran's vital oil sector.
After Pompeo's announcement, Iranian Foreign Minister Mohammad Javad Zarif said Friday on Twitter that the conference would bring shame on the Polish government and invoked how during World War II Iran saved Polish lives.
"Polish Govt can't wash the shame: while Iran saved Poles in WWII, it now hosts desperate anti-Iran circus."
Iran hosted more than 100,000 Polish war refugees who were brought to the country after surviving work camps in the Soviet Union and before they migrated to Israel, New Zealand and some African countries. Scores stayed on after the war, choosing to reside in Iran.
Vice President Es’haq Jahangiri said the summit is being held because US sanctions had failed to bring Iran to its knees.
"Americans thought pressures would break down our economy. They wanted to bring our oil exports to zero but failed... Now they've decided to hold an anti-Iran conference in Europe," Jahangiri said.
Poland’s JCPOA stance
Poland's Foreign Minister Jacek Czaputowicz said Saturday he hoped the conference will provide a new platform for international dialogue and allow the US and European Union to find a closer position on Iran.
Czaputowicz said Poland supported the EU's efforts to preserve the 2015 nuclear agreement with Iran.
Tehran and Warsaw have had good relations. The balance of trade between the two nations was $230 million in 2017, up from 80 million in 2015.
