Nato Secretary General Jens Stoltenberg is scheduled to visit Finland to attend a Nordic Social Democratic parties meeting next week in Helsinki.
The military alliance chief is scheduled to take part in the annual meeting of Samak, the Co-operation Committee of the Nordic Social Democratic parties and trade union labour organisations, on 28 February.
Before his job as head of Nato, Stoltenberg served as Prime Minister of Norway as a member of the social democrats.
Others scheduled to attend the meeting include Finland's SDP leader, Prime Minister Sanna Marin, Danish PM Mette Fredriksen, current Norwegian PM Jonas Gahr Støre, former PM of Sweden Magdalena Andersson as well as Iceland's Gudmundur Arni Stefansson.
Ever since Finland and Sweden applied to become members of Nato, Stoltenberg has encouraged alliance members to ratify their accession.
However, Turkey has pushed back on such requests, particularly regarding Sweden, with Ankara demanding concessions in exchange for approving their membership.
Last week Stoltenberg said that the issue of Finland and Sweden joining Nato together was not the main priority, but rather that they should be ratified as full members as soon as possible.
On Monday, Turkish Foreign Minister Mevlut Cavusoglu suggested that Turkey could ratify Finland's bid to join Nato even before Sweden takes steps towards addressing Turkey's security-related demands.
