On Tuesday, EU interior ministers approved a plan to redistribute 120,000 refugees throughout the bloc according to a quota system proposed by the European Commission.
"Slovakia is a sovereign country and it is a dictate of the majority [implementation of quota system] in a very sensitive issue," Fico said.
Slovakia is required, under quotas mandated by the European Commission, to adopt almost 2,300 refugees under the new refugee resettlement plan.
Europe is currently facing a severe refugee crisis. European Commission estimates some 500,000 people from the Middle East and North Africa have arrived in the European Union since the beginning of 2015, seeking asylum.
