TEHRAN, Jan. 13 (Xinhua) -- Iran's Foreign Ministry summoned Polish charge d'affaires to voice Tehran's protest at the European country's decision to host a conference that the US is going to hold against Iran next month, Tasnim news agency reported on Sunday.

"This is a US hostile move against the Islamic republic, and Poland is expected to refrain from keeping the US company in holding such a conference," an Iranian Foreign Ministry official said.

In response, the Polish diplomat provided an explanation for the conference, saying it would not be an anti-Iran gathering and that Poland's stances differ from those of the United States.

The Iranian official said the explanation was "insufficient," stressing that the Polish government must take immediate action over its decision, otherwise, "the Islamic Republic of Iran will have to take retaliatory measures."

Iran's protest followed US Secretary of State Mike Pompeo's remarks on Friday who said that Washington will jointly host a global summit in the Polish capital Warsaw on Feb. 13-14 focusing on Iran and its role in the Middle East region.
