Kallas said Poland was an "important partner for the Baltic states," in terms of "NATO’s collective security and the region’s connectivity, but also economically."
She added the four prime ministers would "analyse the outcomes of the European Council as well as discuss long-term support for Ukraine and regional cooperation."

The new appointed Polish prime minister has received a "very personal letter" from US President Joe Biden, with "congratulations and proposals for areas of cooperation in the coming weeks and months," Grabiec told the media.
He added that Tusk "has received congratulations from across the world" after taking office earlier this week.
Plan to replace heads of security services
Grabiec also said that Tusk would make "personnel changes in the public administration," starting with "agencies where crimes or abuses of power may have taken place" under the previous conservative government.
Grabiec added that the prime minister had "taken steps" to replace the heads of Poland's security services, including civil and military intelligence, civil and military counterintelligence, and the Central Anti-Corruption Bureau (CBA).
On Wednesday, Tusk requested the opinion of the governmental Security Services Committee, the parliamentary committee on security services and President Andrzej Duda on the planned changes at the top of security agencies, according to officials.
The governmental Security Services Committee has given a favourable opinion, public broadcaster Polish Radio's IAR news agency reported.
