MOSCOW >> President Joe Biden may have his alliance of democracies, but as a video summit on Wednesday underscored, Russia and China still have each other.

President Xi Jinping of China, facing a diplomatic boycott of this winter’s Beijing Olympics from Biden and others, secured a public pledge from President Vladimir Putin of Russia that he would attend — the first national leader to RSVP.

Putin, facing threats of crushing Western sanctions if Russian forces attack Ukraine, heard Xi propose that Russian and China cooperate to “more effectively safeguard the security interests of both parties.”

The videoconference between Xi and Putin on Wednesday — the 37th time the two men had met since 2013, according to Xi — was both a show of solidarity between two autocrats battling Western pressure and a display of the kind of mutually beneficial, increasingly tight partnership their two countries are building.

“We firmly support each other on issues concerning each other’s core interests and safeguarding the dignity of each country,” Xi told Putin, according to reports in the Chinese state news media.

There is still plenty of friction between Russia and China, onetime adversaries that share a land border stretching more than 2,600 miles, over matters like Siberian logging and history. But on trade, security and geopolitics they are increasingly on the same page, forming a bloc trying to take on American influence as both countries’ confrontations with the United States deepen.

The two countries do not have a formal alliance. But Xi told Putin that “in its closeness and effectiveness, this relationship even exceeds an alliance,” according to a Kremlin aide, Yuri Ushakov, who briefed reporters in Moscow on the meeting after it ended.

The two leaders discussed forming an “independent financial infrastructure,” Ushakov said, to reduce their reliance on Western banks and their vulnerability to punitive measures from the West. And they floated a possible three-way summit with India, evidence of their broader geopolitical ambitions; Putin traveled to New Delhi to meet with Prime Minister Narendra Modi last week.

“A new model of cooperation has been formed between our countries — one based on foundations like noninterference in domestic affairs and respect for each others’ interests,” Putin told Xi in televised remarks.

In a bit of symbolic stagecraft, both men spoke with both the Chinese and Russian flags in the frame behind them — in contrast to Putin’s videoconference last week with Biden, when Putin spoke next to only the Russian flag.

Analysts say that an important factor in Russian-Chinese ties is the personal chemistry between Putin and Xi, both men in their late 60s who have consolidated control over their countries’ political systems. Xi addressed Putin as his “old friend,” while the Russian president called his Chinese counterpart both his “dear friend” and “esteemed friend.”

But Xi and Putin came to Wednesday’s meeting with very different near-term priorities. For Xi, the summit was a chance to deflect mounting criticism over China’s actions in crushing the pro-democracy movement in Hong Kong, in menacing Taiwan and in repressing Muslim minority groups in western China, and over a host of lower profile issues.

He hopes to show that China is not isolated diplomatically, especially on the eve of the Winter Olympics, which are intended to showcase China’s global stature, not the souring of its relations with much of the world.

“I expect that in February of next year, we will finally meet in person in Beijing,” Putin told Xi, addressing the Olympics in his televised opening remarks. “We have unfailingly supported each other in questions of international athletic cooperation, including in not accepting any attempts to politicize sports or the Olympic movement.”

For Putin, the talks came at a high-stakes moment in his brinkmanship over Western influence in Ukraine. Karen Donfried, the American assistant secretary of state for European and Eurasian Affairs, was in Moscow on Wednesday for talks on Ukraine. Ushakov said that Russian officials presented her with a proposal detailing Putin’s previously stated demands that the West roll back its military support for Ukraine and rule out the expansion of the NATO alliance to include Ukraine or other countries in the region.

Western officials are alarmed by Russian troop movements near the Ukrainian border, worrying that Russia could be threatening an invasion even as it makes diplomatic demands. The Chinese public account of the meeting mentioned neither Ukraine nor NATO, but appeared to allude to Russia’s security concerns over them.

“China and Russia should carry out more joint actions to more effectively safeguard the security interests of both parties,” Xi told Putin, according to the Chinese account.

The leaders’ united front in the meeting seemed intended as a riposte to the “Summit for Democracy” that Biden hosted last week, widely viewed as an effort to build a bulwark against authoritarian governments like those in Russia and China.

The Russian and Chinese leaders meet or speak often — though only virtually since the pandemic began. What was unusual about Wednesday’s meeting was China’s effort to telegraph its message in advance.

“Close strategic coordination” between the two countries is essential in today’s turbulent world, a spokesman for the Chinese Foreign Ministry said this week.

The militaries of both countries have also stepped up joint exercises and even operations, including in the air and, for the first time in October, naval patrols in the Pacific. They have also pledged to explore space together.

Before Wednesday’s call, Dmitri Rogozin, the head of Russia’s space program, said that a proposed Russian-Chinese lunar station “will be based on principles of equal partnership, transparency and consensus in the decision-making process” — in contrast, he said, to the terms set by the United States in its lunar station project.

Even so, there are limits to this united front.

China has never recognized the annexation of Crimea, for example, nor does Russia side with China on its expansive claims in the South China Sea. They have also stopped short of binding themselves in a formal treaty alliance, preferring to maintain their ability to act independently and flexibly.

“I do not think they are yet at a point where Beijing would endorse any adventurous action in Ukraine, nor would Russia eagerly side with China if the Chinese decided to invade Taiwan,” said Sergey Radchenko, a professor at the Johns Hopkins School of Advanced International Studies Europe who has written extensively on the relationship.

“I would imagine that they would each show a degree of benevolent neutrality toward the other.”
