Hyperbole? To some degree, yes. Hypocrisy? On some fronts, for sure. But to the Biden administration, such lovey-dovey rhetoric between Moscow and Beijing can't be ignored.
In fact, U.S. wariness over the Russia-China relationship has grown to the point where high-level American strategists are weighing how to factor it in as they try to orient U.S. foreign policy to focus more on a rising China. President Joe Biden is expected to discuss Moscowโs ties to Beijing during his Wednesday meeting with Russian leader Vladimir Putin, whom Chinaโs leader, Xi Jinping, has called his โbest friend.โ
For several years, the relationship between China and Russia appeared to be limited to tactical cooperation or temporary partnerships of convenience, a senior Biden administration official told a news outlet in an interview. More recently, however, it seems to be transforming into something more sustained and strategic.
โWhat weโve seen over the course of the last decade is something much deeper and, frankly, more concerning,โ the senior official said. โI think youโd have to say that on some level that this operates as nearly a quasi-alliance.โ
Biden has been briefed on the topic of Chinese-Russian relations and has delved into intelligence about it, the senior official said. The issue also was the topic of a briefing specifically requested by Secretary of State Antony Blinken, a State Department official confirmed.

But at this early stage in Bidenโs tenure, with several key positions unfilled, the administration still needs to work out the best mechanisms to monitor the Beijing-Moscow dynamic, the senior official said.
โItโs going to be incumbent on us to sort of rethink our overall strategy,โ the senior official said. โDo you contain and deeply, negatively engage both? Do you try to differentiate in your approach to try to improve relations with Moscow? These are all incredibly difficult things.โ
The Moscow-Beijing relationship has had several ups and downs. What was then the Soviet Union quickly recognized the Peopleโs Republic of China upon its establishment in October 1949. In the 1950s, both countries had economic ties and gave military support to North Korea in its war with U.S.-backed South Korea.
But relations cooled considerably in the 1960s as both fought for dominance in the communist sphere, with Soviet and Chinese troops even clashing along their shared border. In 1980, China joined the boycott of the Moscow Olympics. By the end of that decade, however, both had agreed to normalize relations.
In more recent years, China and Russia have often worked in tandem on the diplomatic front, especially at multilateral institutions like the United Nations. The countries typically follow each otherโs lead on issues of import to the other. On Syria policy, for example, China often sides with Russia, which has troops in the war-torn Middle Eastern country.
Bilateral trade between both countries is on the rise, having crossed the $100 billion mark. Moscow and Beijing want to double that by 2024.
Perhaps most striking and of greatest concern to the United States is what appears to be increasing military and technological cooperation between Russia and China.
Asked for examples, the senior Biden administration official ticked off several: โAdvanced fighter airplanes, hypersonic technologies, very effective radars โฆ battle integration systems that link different services more effectively, nuclear propulsion with respect to submarines, night vision โ I mean, I could go on and on. Those are all areas that Russia and China have worked closely on together.โ
Analysts Andrea Kendall-Taylor and David Shullman recently pointed out in Foreign Affairs that Russia and China have been conducting joint military exercises โof increasing frequency and complexity.โ The countriesโ technological cooperation, they wrote, โmight eventually allow them to innovate faster together than the United States can on its own.โ
Other analysts have also tried to draw the Biden administrationโs attention to the Moscow-Beijing connection.
โAs they draw closer economically, technologically, militarily and diplomatically, and their cooperation in each of these spheres crosses new thresholds, their combined weight in East Asia and across Central Eurasia swells the challenge far beyond that posed by either alone,โ Thomas Graham and Robert Legvold wrote in a news outlet Magazine earlier this year.
Some previous U.S. officials warn against overhyping China-Russia ties. They note, for instance, that both still do not cooperate seamlessly, and that thereโs plenty of distrust.
Russia has in recent years accused China of stealing its military technology. Moscow also is suspicious of Beijingโs intentions when it comes to energy and other initiatives in the Arctic circle. The two also could find themselves at odds over India. Russia, a major arms supplier to India, has generally had solid relations with New Delhi. Chinaโs relations with India are tense, with both countries engaging in border skirmishes as recently as this year.
Thereโs also the likelihood of Russia feeling increasingly like the junior partner in its relationship with China, and getting resentful. Thatโs especially the case as China expands its economic ties to countries in Central Asia and beyond, places Russia has long considered its turf.
When it comes to Russiaโs economic relationship with China, the latter is far more dominant and dynamic. China is Russiaโs top trading partner, but Russia doesnโt even crack Beijingโs top 10 trading partners. China also is simply a much bigger player in global trade overall: the value of its exports to the United States alone is bigger than the value of Russiaโs exports to the whole world.
โI donโt think we should invest tons of time in trying to erode [the relationship],โ said David Stilwell, who served as assistant secretary of State for East Asian affairs under previous President Donald Trump. โThat will happen on its own as Beijing intrudes into Moscowโs spheres of influence.โ
Putin is well aware of the imbalance of power Russia faces with China. Some analysts even wonder if recent Russian actions, such as increasing its troop presence along the border with Ukraine, is meant to remind the United States that Russia canโt be ignored, even as Biden has made it clear his top geopolitical concern is China.
โReally, no country has played a weak hand more effectively than Putin has, just across the board,โ the senior Biden administration official said.
The senior official added that any U.S. attempt to capitalize on divisions between Moscow and Beijing has to be extremely subtle and careful. Americaโs relationship with both countries already is fraught enough.
โBoth sides are highly attentive to efforts to create tension or to split them, and they are very focused on what I think both perceive is the larger, menacing problem, and that is the United States,โ the senior official said.
The Biden-Putin meeting is a key step toward exchanging views on China, though that will be one of several topics on the agenda. Biden has paid close attention to the issue in briefings with aides and has โa very nuanced understandingโ of the Moscow-Beijing nexus, the senior official said.
That being said, itโs the type of dilemma that can't be solved quickly, if at all, and requires some serious prioritization.
โWe also face the situation that in the short term, the things that are really concerning at an immediate level often emanate from Russia,โ the senior official said. โBut itโs the long-term challenges of China that are most concerning.โ
