Leaders from Spain, Portugal and their former colonies in the western hemisphere are meeting in Costa Rica for the annual Ibero-American summit.
The 21 government leaders are scheduled to discuss new approaches to tackle inadequate funding for education.
Officials say participants will also discuss Cuba's relationship to the international community. On Friday, Panama and Cuba agreed to restore consular relations, months after Havana broke ties with Panama City for pardoning four men involved in an assassination attempt against Cuban President Fidel Castro.
Meanwhile, a strong earthquake hit Costa Rica earlier Saturday, but only scattered damage and minor injuries were reported.
