Hungarian Prime Minister Viktor Orban was in Beijing on Monday for a visit he branded as a "Peace mission 3.0" after recent trips to Moscow and Kyiv.
Orban was greeted at the airport by Chinese foreign ministry spokeswoman Hua Chunying, according to a photo the nationalist leader posted on social media platform X.
He will meet Xi on Monday morning, state broadcaster CCTV said.
Orban's arrival in Beijing follows surprise visits to Russia and Ukraine in the past week since Hungary took over the European Union's rotating presidency at the start of July.
The trip comes a day before NATO is due to hold a summit to mark its 75th anniversary, with setbacks in Ukraine set to dominate discussions.
Orban, the friendliest EU leader towards Moscow, held talks with President Vladimir Putin on Friday about the war in Ukraine during a trip criticised by both Kyiv and the EU, which said it threatened to undermine the bloc's stance on the conflict.
Putin told Orban that Ukraine must withdraw its troops from regions that Moscow has annexed if it wants peace.
EU foreign policy chief Josep Borrell said the Hungarian leader's trip to Russia was purely a bilateral affair and "Orban has not received any mandate from the EU Council to visit Moscow".
In a short statement, the Chinese foreign ministry said the Hungarian leader would meet Xi on Monday "for in-depth communication on issues of mutual interest".
Close to both Xi and the Kremlin, Orban has refused to send weapons to Kyiv, unlike his fellow EU leaders.
China and Russia's strategic partnership has grown closer since the invasion of Ukraine.
Beijing presents itself as a neutral party in the war and says it is not sending lethal assistance to either side, unlike the United States and other Western nations.
It has however offered a critical lifeline to Russia's isolated economy, with trade booming since the conflict began.
Xi visited Hungary in May this year, for the final leg of a European tour that also led him to France and Serbia.
Following a meeting with Orban, Xi said Beijing placed "great importance" on its relations with the EU.
Despite its small size, the Central European country of 9.6 million people has attracted a flood of major Chinese projects in recent years, mostly related to battery and electric vehicle (EV) manufacturing.
The Hungarian government boasted about having around 15 billion euros worth of ongoing projects originating from the Asian country.
Orban has been championing an "Eastern opening" foreign policy since his return to power in 2010, seeking closer economic ties to China, Russia and other Asian countries.
Last October, the Hungarian premier was the sole EU leader to attend the summit for Xi's flagship Belt and Road initiative in Beijing.
