BERLIN: Senior German and Russian government officials have agreed to a rare in-person meeting next month in an effort to ease political tensions over Ukraine, a German government source said on Saturday.

German Chancellor Olaf Scholz’s foreign policy adviser Jens Ploetner and Russia’s Ukraine negotiator Dmitry Kozak agreed to meet after a lengthy phone conversation on Thursday, the source said on condition of anonymity.

The German government has not made any official comment. A spokesman for Kozak declined to comment.

There have been a flurry of phone calls between western leaders and Russian President Vladimir Putin in recent months over Russia’s military build-up on the Ukrainian border and resulting fears of an invasion.

In-person meetings between senior Western and Russian government officials have been few and far between, though U.S. President Joe Biden held talks with President Putin in Geneva last June.

Since taking office this month, Scholz has emphasised the need for dialogue with Russia over its military build-up on the Ukrainian border while joining western allies in backing sanctions should Moscow invade.

Berlin doubts more than Washington whether Russia actually wants to attack Ukraine and is keen to de-escalate tensions, two government sources told Reuters on condition of anonymity.

Critics accuse Germany of being beholden to Putin because of its need for Russian gas, attacking construction of the Nord Stream 2 pipeline between the countries, bypassing Ukraine. Berlin says Nordstream 2 is not political and would be only one of several pipelines transporting Russian gas to Europe.

“The German side’s goal remains to achieve a swift reactivation of the Normandy format,” the German government source said, referring to multilateral talks between Ukraine, Russia, France and Germany.
