"The future implementation of issues being discussed will be reviewed this Friday in Berlin in the Foreign Ministry at the high official level," Seibert was quoted as saying on the official German government website.
The so-called Normandy Group includes representatives from Germany, France, Ukraine, and Russia.
Previously, the foreign ministers of the Normandy Quartet met on February 24 in Paris for a round of consultations on Ukrainian reconciliation.
The leaders of the Normandy four negotiated a truce in the Belarusian capital of Minsk on February 12 between Kiev forces and independence fighters.
The February 12 agreement was signed by the warring sides and came into force on February 15. The peace deal stipulates an observed ceasefire, the withdrawal of heavy artillery away from the line of contact and an all-for-all prisoner exchange, among other steps.
A previous ceasefire agreement reached in September 2014 was not observed and both sides of the conflict traded accusations of violating the truce.
