Writing on his Twitter account, Zarif said, “Reminder to host/participants of anti-Iran conference: those who attended last U.S. anti-Iran show are either dead, disgraced, or marginalized. And Iran is stronger than ever.”
Zarif poured scorn on the meeting and pointed out that the country, then impoverished after invasion by Britain and the Soviet Union, welcomed more than 100,000 Polish refugees during World War II.
"Polish Govt can't wash the shame: while Iran saved Poles in WWII, it now hosts a desperate anti-Iran circus," he tweeted.
He also posted a picture of the 1996 "Summit of Peacemakers" in the Egyptian summit of Sharm el-Sheikh involving then US president, Bill Clinton, Israeli prime minister, Shimon Peres, and Egyptian leader, Hosni Mubarak.
Clinton had spearheaded the conference to boost Peres after a wave of attacks in Israel claimed by Palestinian resistance movement Hamas.
Earlier on Friday Secretary of State Mike Pompeo announced that the meeting would be held in Warsaw from Feb. 13-14 and 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.”
"We'll bring together dozens of countries from all around the world," Pompeo said.
A State Department spokesman acknowledged that Poland, like other European nations, supports the international accord from which Trump exited last year on curbing the Iranian nuclear program in return for economic sanctions.
The Warsaw meeting "sends an important signal that countries with differing views on the nuclear deal can come together to address other critical issues in the region," the spokesman said.
Poland, led by a right-wing populist government, is a longstanding US ally that has better relations with US President Donald Trump than key European powers Germany and France.
Trump has reimposed sanctions on Iran but has found no support among Western governments, which note that Tehran is abiding by the United Nations-backed nuclear accord.
Secretary of Iran’s Supreme National Security Council Ali Shamkhani also reacted to the US announcement of holding the anti-Iran conference.
“When someone who says ‘sanctions with maximum pressure’ are reduced to holding ‘seminars and conferences’, it only means that he has lost the upper hand,” Shamkhani told reporters on Saturday.
