Why does this matter?
China is the only major government that has friendly relations with Moscow as well as economic leverage as the biggest buyer of Russian oil and gas after the United States and its allies cut off most purchases.
Beijing, which sees Moscow as a diplomatic partner in opposing US domination of global affairs, has refused to criticize the invasion and used its status as one of five permanent U.N. Security Council members to deflect diplomatic attacks on Russia.
Zelenskyy earlier said he welcomed a Chinese offer to mediate.
Why did China do this?
Xi’s government has pursued a bigger role in global diplomacy as part of a campaign to restore China to what the ruling Communist Party sees as its rightful status as a political and economic leader and to build an international order that favours Beijing’s interests.
That is a sharp reversal after decades of avoiding involvement in other countries’ conflicts and most international affairs while it focused on economic development at home.
In March, Saudi Arabia and Iran issued a surprise announcement, following talks in Beijing, that they would reopen embassies in each other’s capitals following a seven-year break. China has good relations with both as a big oil buyer.
Last week, Foreign Minister Qin Gang told his Israeli and Palestinian counterparts that his country is ready to help facilitate peace talks.
Wednesday’s statement warned against the dangers of nuclear war, suggesting Beijing might also have been motivated by what it sees as the growing danger of a more destructive conflict.
Mediating between Ukraine and Russia would increase China’s presence in Eastern Europe, where Beijing has tried to build ties with other governments. That has prompted complaints by some European officials that China is trying to gain leverage over the European Union.
Political science professor Kimberly Marten of Barnard College at Columbia University in New York doubted China would succeed in a peacemaker role.
“I have a hard time believing that China can act as peacemaker,” she said, adding that Beijing has been “too close to Russia.”
What are China’s relations with Russia?
China is the closest thing President Vladimir Putin’s isolated government has to a major ally.
Xi and Putin issued a joint statement ahead of the February 2022 invasion that said their governments had a “no limits friendship.”
Beijing has tried to appear neutral but has repeated Russian justifications for the invasion.
Xi received a warm welcome from Putin during a visit to Moscow in March. The Chinese defence minister visited Russia this month.
China has stepped up purchases of Russian oil and gas for its energy-hungry economy, helping to offset lost revenue resulting from Western sanctions. In exchange, China gets lower prices, though details haven’t been disclosed.
Marten said the Xi-Zelenskyy call was “kind of a slap at Russia because Russia has been very keen to portray China as its ally.” She said the direct China-Ukraine contact “indicates China is taking at least a step away from Russia.”
What are China’s relations with Ukraine?
China was Ukraine’s biggest trading partner before the invasion, though on a smaller scale than Chinese-Russian trade.
In 2021, Ukraine announced plans for Chinese companies to build trade-related infrastructure.
Zelenskyy’s government was more ambivalent toward Beijing after it was clear Xi wouldn’t try to stop Putin’s war, but the two sides have remained amicable.
“Before the full-scale Russian invasion, China was Ukraine’s number one trading partner. I believe that our conversation today will give a powerful impetus to the return, preservation and development of this dynamic at all levels,” an official Ukrainian readout of the call reported.
Qin, the foreign minister, promised this month China wouldn’t provide arms to either side, a pledge that benefits Ukraine, which has received tanks, rockets and other armaments from the United States and European governments.
The Chinese ambassador to France set off an uproar in Europe when he suggested former Soviet republics — a group that includes Ukraine — might not be sovereign nations. That was in line with Putin’s comments denying Ukrainian sovereignty.
Beijing then reassured former Soviet states it respected their sovereignty and said the ambassador’s comments were a personal opinion, not official policy.
Elizabeth Wishnick, of the US-based think tank CNA and Columbia University’s Weatherhead East Asian Institute, said in an email: “I wonder if Xi’s call was set up quickly to deflect attention” from the uproar over the Chinese ambassador’s remarks.
