Zelenskyy announced this on Telegram.
"Today, President of Finland Alexander Stubb and I signed an agreement on security cooperation and long-term support. It is a crucial document that shows Finland's readiness to continue supporting Ukraine in the fight against Russian aggression," he wrote.
Finland will provide long-term military and financial assistance, as well as deepen cooperation with Ukraine in the political, financial, humanitarian and reform sectors. Thus, Finland is preparing a four-year plan to support Ukraine, with a budget for development and reconstruction of €290 million.
Helsinki is expected to help Ukraine rebuild its energy sector, assess environmental damage, and strengthen border and critical infrastructure protection. The country will also take part in the treatment of Ukrainian soldiers.
The presidential press service clarified that the document contains "powerful blocks on sanctions, compensation for damages and bringing the aggressor to justice."
The agreement also states that Finland fully supports Ukraine's accession to the EU and NATO.
Zelenskyy thanked his Finnish counterpart for supporting Ukraine, which has reached almost €2 billion since the start of the full-scale war and as of today.
