Duda's top foreign policy aide, Marcin Przydacz, told reporters on Friday that the meeting in the Portuguese city of Porto focused on issues including international security and migration policies.
On Thursday, Duda and Polish Prime Minister Mateusz Morawiecki reiterated their opposition to proposed new EU migration rules and vowed to communicate their criticism to top European politicians at international meetings this week.
In a joint statement to the media, the two leaders said they opposed any plans by the European Union for "mandatory relocation of migrants" across the bloc.
The Arraiolos Group brings together heads of state from EU member countries that have parliamentary rather than presidential models of government, Polish state news agency PAP reported.
The group is named after the small Portuguese town where the first such meeting took place in 2003.
