Frank-Walter Steinmeier, German foreign minister, is predicted during the Tuesday meeting in Berlin to attempt to convince the council's five permanent members to firm up sanctions when negotiating with Iran, Deutsche Welle reported Thursday.
"Iran should not get the impression that the international community lacks determination and solidarity," German Foreign Ministry spokesman Martin Jager said.
Confrontations with Iran have been a challenge for international leaders in the past, the report said. Dealings with the country were made more difficult when a U.S. Intelligence report claimed Iran halted its nuclear weapons plan in 2003.
Steinmeier visited Vienna for meetings Thursday with the director of the U.N. Internal Atomic Energy Agency, Mohammed ElBaradei, who recently decided that Iran had to end limitations during U.N. checks of the country's claims of peaceful nuclear activity.
