The Munich Security Conference concludes on February 17, with a highly anticipated speech by Iranian Foreign Minister Mohammad Javad Zarif on the schedule.
Zarif is expected to respond to efforts by the United States to persuade allies to withdraw from the 2015 nuclear deal that Iran signed with six world powers.
The deal provides Tehran with relief from sanctions in return for curbs on its nuclear program.
U.S. President Donald Trump has withdrawn from the accord, saying its terms were not strict enough to prevent Iran from developing nuclear weapons, and reimposed sanctions. Allies France, Germany, and Britain have said they will remain in the deal despite efforts so far by Washington to have them pull out.
Zarif is also expected to address comments by Pence after his visit to the memorial site of Auschwitz in Poland in which the vice president accused Iran of Nazi-like anti-Semitism.
In an interview with Germany's Spiegel magazine, Zarif called the allegations "ridiculous," adding that not "even the U.S. vice president" should be allowed to exploit the Holocaust for his own purposes.
