Primorac said that Croatia and Bosnia-Herzegovina had to cooperate because they shared the common goal of joining the European Union.
"Croatia does not intend to interfere in political affairs in Bosnia-Herzegovina, but it has the right to know what is going on with the Croats in Bosnia-Herzegovina and has the right to protect their interests to the maximum and assist them in education and science," Primorac said.
Earlier on Friday, Primorac met Bosnian Federation Education Minister Zijad Pasic and Civil Affairs Minister Safet Halilovic in Sarajevo. "Halilovic and Pasic assured me that the equality of all three constituent peoples of Bosnia-Herzegovina, including Croats, will be respected in all education programmes," the Croatian minister said.
Bosnian Croat officials and church dignitaries have warned on several occasions that the Croats are not treated equally in Bosnian education institutions.
Before Mostar and Sarajevo, Primorac had visited the northern town of Odzak and Travnik and Nova Bila in central Bosnia.
