On Tuesday, the Dutch prime minister and his Danish counterpart arrived in South Africa on a joint working visit.
Ramaphosa updated Rutte and Frederiksen on the most recent developments in Russia and Ukraine, the South African Broadcasting Corporation (SABC) reported.
"Among other things, we called for de-escalation of fighting and for negotiations to commence with urgency, for the release of prisoners of war and return of children, for the greater humanitarian support and for the reconstruction to be prioritised," the South African leader was quoted as saying by the SABC.
Rutte said that he appreciated the opportunity to get a debrief about the Ukrainian conflict, as well as some insight concerning developments in Africa, the report said.
Frederiksen, in turn, said that democracies must cooperate in order to promote peace and stability, adding that cooperation is crucial for settling conflicts, according to the SABC.
Later, the Dutch prime minister said on Twitter that cooperation in green hydrogen technologies and the protection of international law were among the most important issues on the agenda.
