Prime Minister Petteri Orpo (NCP) has welcomed the decisions made at an EU defence summit in Brussels on Thursday, which include spending more on defence and continuing to support Ukraine.
Orpo told Yle that Finland had persuaded its EU partners to frontload new support for Ukraine at the emergency meeting.
The summit was called following changes in US policy towards Ukraine.
EU leaders agreed at the meeting to allow Ukraine faster access to money from the Ukraine Support Instrument, which is worth around 50 billion euros.
Thursday's emergency summit was, however, unable to agree to new measures to support Ukraine due to Hungary using its veto, but the 26 other EU states did agree to increase defence spending.
Support for Ukraine will increasingly fall to countries in the so-called "coalition of the willing", composed of around 20 countries inside and outside Europe.
Some of those countries might provide security guarantees for Ukraine, but Finland would not be expected to do so due to its border with Russia, according to Orpo.
"Our soldiers' role is to defend Finland," said Orpo. "It would be a big risk if soldiers from a country bordering Russia were in a situation where conflict might arise."
Orpo added that Finland could participate in a peacekeeping operation, if one were to be established in Ukraine.
He further noted that the strongest peacekeeping force, however, is Ukraine itself.
"Ukraine currently has the strongest army in Europe," said Orpo. "Supporting and equipping it is the best way forward."
Meanwhile, French President Emmanuel Macron has invited military commanders to Paris next week to discuss security guarantees and peacekeeping in Ukraine. Orpo said Finland will be represented at the meeting.
Increased European spending on defence is welcome, according to Orpo, but he stressed that keeping the United States engaged in European defence is a priority.
