President Volodymyr Zelenskyj is due to meet Norway’s king and prime minister on Tuesday. He will also meet Finland’s president and an American envoy. The talks are expected to address the kidnapping of Ukrainian children. The announcement does not say which official will lead each delegation or whether the children have already been returned. It also gives no indication of the specific demands Ukraine intends to make. The meeting is set to bring senior figures from four countries together around the issue.
