"Russia is an important player on the world stage and as a permanent member of the (U.N.) Security Council it’s also indispensable when it comes to solving political conflicts,” Seibert said. Germany is currently a non-permanent member of the Security Council.
Merkel has already spoken with Turkish President Recep Tayyip Erdogan on Monday about the situation in the Middle East, Seibert said.
Germany has offered to mediate between all parties following the killing of Iranian Gen. Qassem Soleimani in a U.S. airstrike in Iraq last week.
Foreign Minister Heiko Maas, who will accompany Merkel to Moscow, spent “all weekend on the phone” with his European and American counterparts, his spokesman Rainer Breul told reporters.
He added that talks with the Iranian foreign minister were planned “soon.”
Germany may struggle to portray itself as an honest broker between Washington and Tehran, however.
Iran summoned Germany's charge d'affaires in Tehran to the foreign ministry Sunday to express annoyance over comments by German officials that suggested Berlin considered Soleimani's killing to be justified.
Asked to elaborate on about Germany's stance, Merkel's spokesman said that the killing of Soleimani “was preceded by Iranian actions,” citing attacks on Saudi Arabian oil facilities, tankers in the Strait of Hormuz and the U.S. Embassy in Baghdad.
“We have always stressed, and perhaps this is an opportunity to do so once more, that we see these regional activities by (Iran) in particular in a very critical way and that they play a negative role in this region," Seibert said.
