Hungarian Prime Minister Viktor Orban this week invited Kristersson to Budapest to discuss the issue “at your earliest convenience”, an invitation Kristersson on Thursday accepted.

“I’m happy to go to Budapest … We have a lot to talk about … but we’re not negotiating the Nato membership, there are no negotiations on this,” Kristersson told Swedish television TV4.

“But we could talk about how we will best cooperate in Nato,” he said.

Swedish Foreign Minister Tobias Billström on Tuesday said there was “no reason to negotiate” with Hungary.

Kristersson said Friday that while he was willing to travel to Budapest, a meeting with Orban at the European Union Council in Brussels on February 1st was more practical.

“We’ll see each other on Thursday next week at the European Council and we can begin discussing things then,” he said.

For a visit to Budapest, “we’d have to find a date for this, things like this aren’t usually done in haste. I suspect that his calendar, like mine, is quite full.”

Orban’s invitation came just days after Hungary criticised Sweden for not taking steps to strengthen bilateral relations.

Budapest has often denounced what it called Sweden’s “openly hostile attitude”, accusing Swedish representatives of being “repeatedly keen to bash Hungary” on rule-of-law issues.

• What happens next for Sweden’s Nato application?

Orban said nonetheless on Wednesday that he had reaffirmed his “support” for Sweden’s membership to the security alliance in a phone call with Nato chief Jens Stoltenberg.

Sweden and Finland dropped decades of military non-alignment and applied for Nato membership in response to Russia’s invasion of Ukraine nearly two years ago.

Finland became the 31st nation of the alliance last April.

Nato membership applications require unanimous ratifications by all alliance members.

After more than a year of delays, Turkey’s parliament ratified Sweden’s bid on Tuesday and President President Recep Tayyip Erdogan signed the formal accession protocol on Thursday.
