"The Arraiolos Group summit has come to an end," Nawrocki said in an X post on Friday.
"I would like to thank all the leaders for the substantive and constructive discussions, which focused on security in our region and the possibilities for using artificial intelligence in the civilian and military sectors," he added.
The Arraiolos Group brings together heads of state from European Union countries with parliamentary rather than presidential systems of government, Poland’s PAP news agency reported.
The format was launched in 2003 in the Portuguese town of Arraiolos.
During his two-day visit to Estonia on Thursday and Friday, Nawrocki also held bilateral talks with Estonian President Alar Karis and met with government and parliamentary leaders in Tallinn to discuss security cooperation.
Nawrocki last month discussed regional security with the Lithuanian president and prime minister in Vilnius.
He is scheduled to visit Latvia later this year for further talks with Baltic leaders.
