While Hungary just assumed the EU's rotating presidency this month, Orban has already met with Ukrainian President Volodymyr Zelenskiy in Kyiv and been received by the Kremlin, a trip that drew a
strong rebuke from his allies.
"Peace Mission 3.0.," Orban, a critic of Western military aid to Ukraine and the EU leader with the warmest relations with Xi and Putin, said on his official X account as he touched down in Beijing.
China, which has close ties to Russia, has been promoting a six-point peace plan it issued with Brazil in May, proposing an international peace conference "at a proper time" and calling for equal participation by both Ukraine and Russia.
Ukraine is hoping to win broad global backing for its proposals on how to end the war with Russia before beginning discussions with Putin, holding a huge
international summit last month in Switzerland to which Moscow was not invited.
But Kyiv's aim of ostracising Russia is meeting resistance. China sat out the Swiss meeting and has won backing from Moscow for its own peace plan. Indian Prime Minister Narendra Modi is expected to visit Russia later this week, with Ukraine likely to be on the agenda.
"The international community should create conditions for the resumption of direct dialogue and negotiations between the two sides and provide assistance," Xi told Orban, according to Chinese state media.
"It is in the interests of all parties to seek a political solution through an early ceasefire," he added.
Orban said China was "a key power in creating the conditions for peace in the Russia-Ukraine war", giving that as the reason for his meeting with Xi just two months after the Chinese leader visited Budapest.
Orban's trip to China comes days ahead of a
NATO summit in Washington D.C. that will address providing further support to Ukraine and which he is due to attend.
While some EU leaders have been quick to say Hungary's EU presidency does not mean Orban represents the 27-strong bloc, Xi told Orban that China hoped Hungary would "play an active role in promoting the healthy and stable development of China-EU relations".
In Germany, Vice Chancellor Robert Habeck said on Monday Orban does not speak for Europe and that Hungary's politics often do not represent the core of EU thinking.
