Hungary's Prime Minister Viktor Orban called on Ukraine to work toward a "quick ceasefire" in order to speed up peace negotiations with Russia to put an ultimate end to the war.

Orban issued the appeal standing next to President Volodymyr Zelenskyy during a surprise visit to Ukraine, the first by the vocal critic of Western support for Kyiv.

"I asked the president to consider whether... a quick cease-fire could speed up the peace talks," Orban told reporters, adding that the cease-fire he envisions would be "time-limited."

Ukraine has repeatedly rejected calls for a pause in fighting, which it says would just give Russia time to regroup for a fresh assault.

The United States meanwhile on Tuesday announced new security aid for Ukraine worth $2.3 billion.

In October 2023 Orban met Russian President Vladimir Putin at a summit in Beijing, becoming the first EU leader to do so since the start of the war.

The leader, in power since 2010, regularly criticizes Europe's financial and military support for Kyiv, temporarily blocking a 50-billion-euro ($53-billion) aid package for weeks.

And he openly opposes holding EU membership talks with Kyiv as well as Brussels' sanctions on Moscow – though Budapest has not used its veto to block the moves.

A 'just peace'

The visit comes the day after Hungary took over the EU's rotating presidency, a position which gives the central European state sway over the bloc's agenda and priorities for the next six months.

Orban said he would report on his talks with Zelenskyy to EU prime ministers "so that the necessary European decisions can be taken."

Zelenskyy said the timing of the visit was symbolic.

"This is a clear indication of our common European priorities, of how important it is to bring a just peace to Ukraine," he said, urging European countries to maintain military support.

As the two leaders talked in Kyiv, yet more civilians were reported dead from Russian bombardments.

Moscow's forces killed two elderly women and injured nine in Nikopol, a city in southern Ukraine, the local governor said.

And a Russian strike killed one person and wounded seven more in the southern Kherson region, which is partially occupied by Russia's forces.

Asked about Orban's visit earlier on Tuesday, the Kremlin said it expected little to come of it, but described him as a "tough" politician who keenly defended his country's interests.

Hours after the talks in Kyiv, Moscow said Foreign Minister Sergei Lavrov held a phone call with Hungarian counterpart Peter Szijjarto in which the "Ukrainian crisis" was discussed.

Relations have been frosty between Orban and Zelenskyy since the start of the war.

After winning re-election in April 2022, Orban said the Ukrainian leader was an "opponent" he had managed to defeat in the campaign after Zelensky had personally called him out over a lack of support in the first days of Russia's invasion.

In December, Zelenskyy sought out the Hungarian leader at the inauguration of Argentine President Javier Milei for what he called a "frank" conversation.

Videos circulated online showing the pair locked in a tense exchange.

They were again filmed in a short, animated exchange, last week on the sidelines of an EU Council meeting in Brussels.

Speaking in Kyiv on Tuesday, Orban said he wanted to "see much better relations" between Hungary and Ukraine, adding that he was "trying to put the discussions of the past behind us."

Hungary wields considerable influence over the West's support for Ukraine given its membership of both the EU and NATO, giving it the ability to thwart, delay, water down or outright block initiatives and funding.

But Orban's call for a cease-fire before substantive peace talks get underway is likely to be a non-starter.

Last month, Putin demanded Ukrainian troops abandon even more territory in the south and east if it wanted the fighting to stop – demands rejected by Zelenskyy as an "ultimatum" reminiscent of Adolf Hitler.

The Ukraine leader is also seeking to marshal international support behind his plan to end the war – one that sees Russian troops fully withdraw from the country, including the Crimean peninsula Moscow annexed in 2014, and pay for the destruction wrought since the February 2022 invasion.

At a major peace summit in Switzerland last month Hungary agreed with a document that called for Ukraine's "territorial integrity" to be respected in any final peace settlement.
