Borrell said the meeting planned for Budapest in late August would now take place in Brussels after Hungarian Prime Minister Viktor Orban visited Moscow and Beijing without EU backing and his government branded EU policy as "pro-war."

"We have to send a signal, even if it is a symbolic signal," Borrell told reporters in Brussels after a last meeting of EU foreign ministers before the summer break.

At Monday's meeting, many EU foreign ministers voiced strong condemnation of Budapest's stance directly to their Hungarian counterpart, Peter Szijjarto, according to officials.

"This was very clear and was reiterated in a way that left no room for doubt," Portuguese Foreign Minister Paulo Rangel said.

Many EU countries consider Hungary to be too close to Moscow, undermining EU efforts to isolate Russia politically and diplomatically over its 2022 invasion of Ukraine. Hungary says it is trying to bring peace to Ukraine as soon as possible.

Borrell said Budapest should be branding Russian President Vladimir Putin "pro-war", not the European Union.

"If you want to talk about the war party, talk about Putin," he said.

Anticipating the move before it was announced on Monday, Szijjarto branded Borrell's decision "childish."

"I really don't want to offend anyone, but it's probably a kindergarten-level debate," he told reporters.

Borrell said there had been no consensus among EU members over whether to attend the meeting - planned for Aug. 28-29 - and a gathering of defense ministers afterward.

He said he opted to switch both meetings to Brussels given that a majority of countries wanted to send a signal to Hungary.

Polish Foreign Minister Radoslaw Sikorski said he had proposed holding the foreign ministers meeting in Ukraine, but Hungary voted against the proposal.
