Haavisto comments on the matter during the security conference in Munich.
According to him, he has discussed the matter with Turkish Foreign Minister Mevlüt Cavusoglu this week.
Finland still wants to join NATO together with Sweden, but more and more people are open to Finland joining first.
Turkey has hinted at it, and now NATO chief Jens Stoltenberg and Finland's defense minister clearly state that this may be the case.
Stoltenberg notes that NATO's position is still that the countries should enter at the same time, but at the same time says:
- But if only one is ratified, then Finland will join, he says.
President Sauli Niinistö is a little more vague in his wording, but his conclusion is similar.
- We applied jointly with Sweden, says Niinistö, but adds that the matter is now in Turkey's hands.
"Can't retract"
He says that, bit by bit, he has heard the message from Ankara change in the direction that the Turkish parliament can say yes to Finland but wait with Sweden.
He emphasizes that Finland cannot imagine accepting such a division, but the situation is such that Turkey could do it anyway.
- It makes the situation difficult for us, our hands are tied behind our backs.
We cannot withdraw our application, says President Niinistö.
Finnish Defense Minister Mikko Savola also says on the spot in Munich that Finland will not try to delay the process to wait for a Swedish yes as well.
- No, no, then we will join, he says in an AP interview.
The ambition is fixed
The country's Prime Minister Sanna Marin emphasizes, however, that the ambition for both countries to get a yes from Turkey at the same time remains firm.
Our message to Turkey and, for that matter, Hungary, which has also not ratified, is that we want to join NATO at the same time.
It is in everyone's interest, she said during a conversation on stage during the security conference.
But she still interjects that "there may be national ratification processes that can have an impact".
In connection with the conference, today Prime Minister Ulf Kristersson (M) also met Jens Stoltenberg and Sauli Niinistö.
