Croatian Foreign Minister Gordan Grlic-Radman announced in Brussels on Wednesday that Croatia, too, would expel some of Russian diplomats, as had been done by many EU and NATO member states.

“We will do that out of solidarity and in response to what is going on, these horrific scenes from Bucha and other areas of Ukraine,” Grlić Radman said on arrival for a meeting of NATO foreign ministers.

He said that those scenes were reminiscent of Vukovar, its heroic defence and sacrifice 30 years ago.

A number of NATO and EU member states have decided to expel some of Russian diplomats following reports of mass graves and killings of civilians in the Ukrainian town of Bucha after the withdrawal of Russian troops.

On Wednesday evening and Thursday, the foreign ministers of the 30 NATO countries will discuss sending further aid to Ukraine, including anti-tank weapons, anti-aircraft systems, cyber support, and protective equipment against chemical and biological threats.

On Thursday, they will be joined by Ukrainian Foreign Minister Dmytro Kuleba, who will report on the latest developments, including talks between Kyiv and Moscow.

The meeting will be attended by Finland, Sweden, Georgia and the European Union, as well as Asia-Pacific partners Australia, Japan, New Zealand and South Korea.

Also discussed will be the new Strategic Concept, which is expected to be adopted at the alliance summit in Madrid in late June.

“We are preparing the new Strategic Concept so that the alliance can respond to all forms of threat and be more efficient and stronger,” Grlic-Radman said.

He said that the document would retain the open-door policy towards enlargement, stressing that Croatia supported the integration of the Western Balkan countries into NATO.
