When Russian President Vladimir Putin and Chinese leader Xi Jinping met in Beijing for the opening of the 2022 Winter Olympics, they confidently outlined their vision for a new international order no longer dominated by the United States and its democratic allies.

Now, nearly two years on, and with geopolitical fault lines hardening globally, the world's two most powerful autocrats are preparing to see each other again in the Chinese capital.

The meeting comes under the shadow of conflict, with Russia's grinding invasion of Ukraine -- launched just three weeks after the leaders' last get-together in Beijing -- and Israel's war against Hamas, which now threatens to escalate regionally.

Both Beijing and Moscow have criticized Israel's actions in response to a shock attack by Palestinian militant group Hamas last week and called for a ceasefire, in the latest showing of the two powers' efforts to step up their alternative leadership to that of the United States, which affirms Israel's on-going right to retaliate.

Xi and Putin are likely to discuss the situation during a meeting this week as Putin arrives as a guest of honor at the Belt and Road Forum in Beijing -- an exceptionally rare foreign trip for the diplomatically isolated leader.

Heads of state, representatives and delegations from more than 140 countries are expected to attend China's landmark, two-day diplomatic event beginning Tuesday, which marks 10 years since the start of Xi's global infrastructure funding drive, and presents the Chinese leader with an opportunity to project Beijing's growing global ambitions.

A rare trip

Putin, who has seldom left the bloc of former Soviet nations since launching his war, is shunned by the West and wanted by an international court for alleged war crimes. Experts say he is also unwilling to travel anywhere he feels his personal security can't be absolutely assured. He made his first known trip of the year outside of Russian-controlled territory last week, with a visit to Kyrgyzstan.

But despite Putin's changing circumstances since his last time in Beijing, the two leaders have become increasingly aligned in presenting an alternative world view to the one offered by the West -- as they seek to bring more countries alongside their efforts to shift a global balance of power they feel is stacked against them.

In an interview with China's state broadcaster ahead of the event, Putin lavished praise on Xi, calling the Chinese president "steady, calm, pragmatic and reliable -- a true world leader," and hailing his "unique approach of dealing with other countries" that has shown no imposition or coercion, but rather provided others with opportunities.

Putin and Xi, who frequently refer to their close friendship, have met 40 times in the past decade, including twice since the start of the war in Ukraine. During their previous meeting in Beijing, the two men released a 5,000-word joint statement declaring a friendship with "no limits" and underscoring their deep alignment against the West.

Attending the forum will be a significant opportunity for Putin to "achieve international exposure ... and show that Russia still has a strong friend in China," said Li Mingjiang, an associate professor of international relations at Singapore's Nanyang Technological University.

"And for China, having an important international player like Putin to join the BRI summit is also politically important," he added. Otherwise, the forum -- the crowning event of Xi's diplomatic year -- is largely expected to include leaders from less-influential developing and middle income nations.

'No limits' no more?

Russia's invasion of Ukraine put the growing China-Russia relationship to the test like no other event in recent history, placing Beijing under heavy scrutiny from Western nations for its close ties to its northern neighbor and raising questions about whether Xi had advance knowledge of Putin's plan.

Beijing has since claimed neutrality in the conflict and called for peace, in recent months ramping up efforts to be seen as a potential peace broker, as concerns about its close ties with Russia further strained its relations with Europe and the United States.

But the world's second largest economy has also become a key lifeline for a sanction-ridden Russia, which is now dependent on it for goods and energy purchases, and the two countries have deepened their interactions across a range of areas since the start of the war.

Last year, Russia and China saw record trade, which continued to grow in 2023. They've expanded security cooperation through more joint military drills and robust official dialogue, experts say, and continued to deepen diplomatic ties -- including those of Putin and Xi, who earlier this year chose a state visit to Moscow as the symbolically significant first foreign trip of his third term as China's President.

"China tries rhetorically and symbolically to put a certain distance between itself and Russia when it comes to talking to Western audiences," said Alex Gabuev, director of the Carnegie Russia Eurasia Center think tank in Berlin.

"(But) even if it's officially not dubbed a 'no limits partnership,' (the China-Russia relationship) has become, in real terms, more solid, robust, and deep," he said.

Push for peace?

The timing of the Beijing hosted forum, coming as Israel signals it may launch a ground invasion of the Hamas-governed Gaza strip, presents Putin with opportunity to shift the global spotlight away from his war in Ukraine, analysts say.

Moscow is expected to table a United Nations Security Council resolution calling for a ceasefire, without naming Hamas, with its UN envoy on Friday comparing the day-after-day shelling of Hamas-controlled Gaza by Israel to the brutal siege of Leningrad during World War II.

At the other end of the historical spectrum, US President Joe Biden this weekend described Hamas' attack as the worst massacre of Jews since the Holocaust.

China has said it will send its envoy to the Middle East to encourage talks and condemned "all acts that harm civilians," but it has not explicitly targeted that condemnation at Hamas, nor named the group in its statements.

During a flurry of diplomatic calls in recent days, Chinese Foreign Minister Wang Yi said Israel's actions have "gone beyond the scope of self-defense."

Both countries' statements stand in contrast to that of the US, which has made clear its staunch support for Israel -- and signaled it does not feel this is the appropriate moment for a ceasefire.

Xi and Putin are expected to discuss the conflict in their upcoming meeting -- where Russia's war in Ukraine will also likely feature.

In that conflict, too, China has tried to position itself as a potential mediator.

But when its comes China's interest in pushing the Russian leader to end his invasion, Xi may be cautious not to take any step that could damage relations.

That's especially as he is likely watching a potential shift in global positions on the conflict, amid signs of changing attitudes at least in some parts of Europe -- and an upcoming election in the United States next year could trigger a significant shift in the level of US support for Ukraine.

"So far we don't see any sign that China is keen to use its upper-hand (to put pressure on Russia)," said Li in Singapore.

"Chinese policymakers don't want to see even the slightest level of distrust between Beijing and Moscow."
