"I have conveyed Croatia's readiness to hospitalise about ten COVID-19 patients each from the Czech Republic and Slovakia, if necessary, taking into consideration the fact that their respective health systems are under strain," Plenković wrote on his Twitter account.
Croatia is showing its solidarity with EU member-states in the struggle against COVID-19, he underscored.
The Czech Republic, which has been one of the hardest hit countries in the world by the COVID epidemic recently, has asked Germany, Switzerland and Poland to take in dozens of COVID-19 patients as the situation in its own hospitals has reached a critical point.
Slovakia has already transferred some of its patients abroad this week.
Poland and Germany each have said that they can hospitalise ten patients from that country.
