On September 2, at the Eastern Economic Forum, Russian Energy Minister Sergei Tsivilev revealed that President Vladimir Putin had renamed the planned “Power of Siberia 2” natural gas pipeline to “Power of Baikal.” According to Russia’s current plans, this second major Sino-Russian gas corridor will stretch eastward from the Yamal Peninsula and western Siberia, passing through Mongolia into China. It boasts a designed annual capacity of 50 billion cubic meters (bcm)—surpassing the approximately 38 bcm capacity of the existing China-Russia eastern route.

An energy artery of this scale, destined to carry tens of billions of cubic meters of natural gas, naturally raises a critical geopolitical question: If Sino-Mongolian relations were to sour, or if Russia leveraged its influence over Mongolia’s energy supply, could Ulaanbaatar restrict gas transit and create a strategic chokehold on China?

While third-country transit inherently introduces political risk, situating “Power of Baikai” within the broader context of Sino-Russian-Mongolian trade, energy, and market dynamics reveals a different reality. Although Mongolia may control the geographic valve, weaponizing it against China would come at an exorbitant cost. More importantly, compared to the original western route proposal—which would have bypassed third countries to enter China directly from Russia—routing the pipeline through Mongolia into northern China aligns far better with the geographic distribution of China’s natural gas demand.

The Economic Logic of the Central Mongolian Route

As early as 2006, Beijing and Moscow proposed piping natural gas directly from western Siberia into China’s Xinjiang region via Russia’s Altai Republic. Commonly known as the “Altai Pipeline” or the Sino-Russian western route, this option was shorter and capitalized conveniently on existing gas fields and infrastructure in western Siberia.

However, regarding China’s broader natural gas infrastructure layout, the Mongolian route offers comprehensive advantages that the western route simply cannot match. Xinjiang is already a major domestic gas-producing region and the primary gateway for Central Asian gas. Currently, imports from Turkmenistan, Kazakhstan, and Uzbekistan enter via Xinjiang and must travel thousands of kilometers through the West-East Gas Pipeline system to reach consumers in northern, eastern, and coastal China. Funneling Russian gas into Xinjiang via the Altai region would only exacerbate this western supply bottleneck, burdening the network with steep, long-term eastward transmission costs.

The Mongolian route fundamentally resolves this issue. Russian gas flowing south through Mongolia would enter China via Inner Mongolia, placing it right on the doorstep of core northern consumption hubs like the Beijing-Tianjin-Hebei region and Shandong province. From there, it could seamlessly integrate with the Shaanxi-Beijing pipeline network and the national trunk grid, allowing for flexible distribution to eastern China. For a strategic pipeline with a 50-bcm annual capacity and a multi-decade lifespan, minimizing the distance between the entry point and end-user markets is crucial for optimizing infrastructure investment, lowering operational costs, and maximizing commercial returns.

From an engineering perspective, the Mongolian route is also far more pragmatic. The Altai Mountains and the borderlands adjacent to Xinjiang feature treacherous mountainous terrain, complex geological structures, and protected environmental zones—including the “Golden Mountains of Altai” World Heritage site—making pipeline construction exceptionally difficult. Conversely, Mongolia’s landscape primarily consists of open steppes and deserts with sparse population density, providing a highly favorable environment for constructing large-diameter, high-pressure natural gas pipelines. Thus, while the Mongolian route introduces a transit country, it circumvents the engineering nightmare of the Altai Mountains and drastically reduces the burden of domestic eastward transmission.

Theoretically, Russia could opt to route western Siberian gas further east, running a new pipeline parallel to the existing “Power of Siberia” corridor to enter China via Heilongjiang, thereby eliminating third-country transit entirely. However, this alternative is far from cost-free.

The current “Power of Siberia” pipeline primarily serves the Kovykta and Chayanda gas fields in eastern Siberia, and its capacity is already saturated by long-term supply contracts. Pumping an additional 50 bcm of Yamal and western Siberian gas through this corridor would require massive new infrastructure spanning the breadth of Russia, including parallel pipelines along the eastern route. Furthermore, once the gas entered Heilongjiang, it would still require long-distance southward transportation to reach major demand centers in northern and eastern China.

While this approach would neutralize the Mongolian transit risk, it would exponentially inflate construction, transportation, and maintenance costs. It would also concentrate Russian gas imports at a single bottleneck in northeastern China. Ultimately, despite the third-country variable, routing the gas directly through Mongolia into Inner Mongolia offers shorter terminal transmission distances and diversifies China’s strategic entry points.

Mongolia Holds the Valve, But China Holds the Market

To gauge whether Mongolia would actually dare weaponize its transit position, one must look at the underlying economic structure between the two nations. In 2025, Mongolia’s total foreign trade stood at approximately $27 billion, with Sino-Mongolian trade accounting for $18.7 billion—a staggering 69.2%. Of Mongolia’s $15.7 billion in total exports, 89.4% went to China. Coal and copper concentrate alone comprised 82.3% of these exports. For a landlocked, mineral-dependent nation of 3.5 million people, Chinese procurement volumes and border port efficiency directly dictate domestic mining output, logistics, fiscal revenue, and employment. Should Ulaanbaatar restrict the flow of “Power of Baikai” and trigger a serious political dispute, the fallout would inevitably spill over into its vital mineral trade, port operations, and foreign investment.

Mongolia is simultaneously bound by deep constraints with Russia. According to April 2026 data from Mongolia’s Ministry of Industry and Mineral Resources, roughly 97% of the country’s petroleum product imports originate from Russia. This extreme dependence leaves Mongolia’s domestic fuel supply highly vulnerable to Moscow’s sway. When Ukrainian strikes on Russian refineries coincided with peak Russian domestic demand in the summer and autumn, tightened Russian oil exports caused Mongolian fuel costs to spike, forcing local gas stations to ration sales. More critically, the extraction and transport of coking coal—the lifeblood of the Mongolian economy—rely almost entirely on diesel. Fuel shortages directly paralyze coal mining and logistics, severely magnifying domestic economic pressure.

Consequently, Mongolia finds itself in a unique state of bilateral dependence: its energy lifeline is tethered to Russia in the north, while its economic engine relies on China in the south. This structural reality means Mongolia cannot easily side with one neighbor while bearing the cost of long-term confrontation with the other. It may sit physically in the middle of the pipeline, but it is firmly boxed in by the overriding practical interests of its two giant neighbors.

A Russian Gas Shutoff: Strategic Self-Harm

Another lingering concern is whether Moscow might leverage its energy grip on Mongolia to force Ulaanbaatar into restricting gas flows to China. However, this hypothetical must be evaluated against Russia’s own vital economic interests.

In 2025, Russia exported approximately 38.8 bcm of gas to China via the eastern route, a 25% year-on-year increase. Conversely, Russia’s pipeline gas exports to Europe have cratered. Its share of EU imports plummeted from around 45% in 2021 to roughly 12%, with volumes collapsing from 152 bcm to just 36 bcm. In just a few short years, Russia’s traditionally Europe-centric export model has been completely upended. The Yamal and western Siberian fields slated to feed “Power of Baikai” were originally developed for European consumers. With that market now radically diminished, Moscow desperately needs a new long-term buyer for hundreds of billions of cubic meters of pipeline gas. Globally, China is the only market capable of consistently absorbing volumes of that magnitude.

Given this reality, if Russia were to pour massive investments into a multi-thousand-kilometer, 50-bcm pipeline, only to subsequently pressure Mongolia into choking off the flow, Moscow would bear the brunt of the damage. It would face plummeting gas revenues, severely reduced pipeline utilization, and stranded upstream capacity. Furthermore, pipeline gas lacks the fungibility of oil. While crude can be easily rerouted to other global buyers via oil tankers, a fixed pipeline aimed at China cannot magically summon alternative buyers of equivalent scale.

Therefore, the notion of Russia manipulating Mongolia into a gas shutoff effectively amounts to strategic self-harm. Astronomical sunk costs and a profound reliance on the Chinese market make the economic toll of an intentional supply interruption prohibitively high for Moscow. Russia may control the valve at the source, but it is ultimately China that determines whether that gas translates into actual export revenue.

50 BCM is Significant, But Not Existential for China’s Energy Security

In 2025, China’s domestic natural gas production reached 262.06 bcm, complemented by 176.46 bcm in imports. Against this backdrop, the 50 bcm annual supply from “Power of Baikai” would represent roughly 11% of China’s total natural gas consumption. In short, while the pipeline would undoubtedly become a crucial energy artery, it would by no means be a single point of failure for national energy security.

This is not to say the Mongolian transit risk should be entirely dismissed. Fifty billion cubic meters still equates to nearly 30% of China’s annual gas imports. Should a supply of this magnitude be suddenly severed during the peak winter heating season, it would undoubtedly trigger short-term, localized supply crunches, spike spot market prices, and necessitate costly cross-regional dispatching and emergency LNG procurement.

However, accurately assessing this risk requires viewing China’s gas supply system holistically. Currently, domestic production accounts for about 60% of total supply, while imports are highly diversified. Onshore pipeline gas flows from Central Asia, Russia, and Myanmar, while seaborne LNG arrives from suppliers like Australia, Qatar, and Malaysia. Consequently, a temporary disruption along the Mongolian route would be met with a variety of stopgap measures, including ramping up domestic extraction, increasing flows through Central Asian or alternative Russian pipelines, and sourcing additional international LNG.

China’s rapidly expanding gas storage and pipeline networks further bolster this resilience. According to 2026 data from the National Energy Administration, national gas storage capacity has more than doubled from 23.4 bcm in 2020 to 54 bcm, while annual LNG receiving capacity now exceeds 120 million tons. While storage capacity does not equate to annual baseload supply, it provides a vital buffer to absorb short-term shocks lasting weeks or even months. Thanks to an interconnected national grid, northwestern Central Asian gas, coastal LNG, and domestic reserves can be dynamically rerouted across regions. Ultimately, a short-term disruption via Mongolia would manifest as temporary price volatility and logistical headaches rather than a catastrophic, nationwide energy crisis.

Post-Construction: Mongolia Will Be Locked into the Value Chain

Once “Power of Baikai” becomes fully operational, Mongolia’s own domestic interests will be fundamentally realigned. The pipeline will deliver a steady stream of transit fees, tax revenues, infrastructure investments, and jobs. It may also help meet Mongolia’s domestic energy needs and spur the development of ancillary infrastructure like roads, telecommunications, and power grids along the route. Over its multi-decade lifespan, this energy artery will invariably cultivate a robust ecosystem of local governments, enterprises, and industrial interest groups heavily invested in its uninterrupted operation.

Recent data validates this trend: in 2025, Mongolia’s coal and copper concentrate exports generated $5.77 billion and $5.81 billion, respectively, totaling nearly $11.6 billion. In recent years, Ulaanbaatar has aggressively expanded its railways and border ports with the explicit goal of increasing mineral exports to China. Clearly, ensuring the frictionless operation of cross-border infrastructure is already a paramount economic imperative for Mongolia.

The natural gas pipeline will forge similar, deeply entrenched economic constraints. Halting a 50-bcm transnational corridor would not only torch Sino-Mongolian relations but also instantly vaporize transit revenues, severely strain relations with Moscow, and eviscerate Mongolia’s international credibility as a reliable partner. For a nation whose entire 2025 foreign trade totaled $27 billion—$18.7 billion of which was with China—the geopolitical and economic price of such a provocation is simply too exorbitant to entertain.

The Real Strategic Risk: An Overreliance on Russian Gas

From a macro-strategic perspective, the genuine long-term risk to China may not stem from Mongolia at all. As long as Beijing maintains a highly diversified energy portfolio, the leverage any single transit country can wield remains inherently capped. The real factor that could shift China’s strategic vulnerability is whether Russian natural gas claims an outsized share of China’s total consumption moving forward.

If the eastern route continues to scale up, the Far Eastern route comes online, and the 50-bcm “Power of Baikai” is completed, Russia’s total gas supply capacity to China could comfortably exceed 100 bcm annually. Should floods of cheap Russian pipeline gas inundate the Chinese market over the long term—gradually crowding out Central Asian gas, seaborne LNG, and higher-cost domestic production—China’s energy grid could inadvertently sleepwalk into an overdependence on a single supplier.

This perfectly encapsulates why Beijing has exercised remarkable strategic patience regarding “Power of Baikai.” While Moscow has repeatedly telegraphed that a final deal is imminent, Beijing has remained highly disciplined, meticulously negotiating price, contract durations, procurement volumes, and construction logistics. For China, absorbing an additional 50 bcm of Russian gas is an excellent way to lower import costs and optimize the northern energy grid. However, it must simultaneously preserve its “strategic redundancies”—maintaining Central Asian pipelines, LNG terminals, domestic production, and robust storage facilities, even if they come at a higher financial premium.

As long as this diversified architecture remains intact, a Mongolian transit node will never constitute a fatal strategic soft spot. China is managing a highly dynamic, interchangeable, and risk-mitigated energy ecosystem—not rolling the dice on a single, isolated pipeline to dictate its energy destiny.

The Asymmetric Interdependence of a Trilateral Pipeline

Placed within the grand geopolitical narrative of the Sino-Russian-Mongolian triangle, “Power of Baikai” represents a textbook case of structural asymmetric interdependence. Russia controls the upstream gas, Mongolia guards the transit throat, and China anchors the entire system with its massive end-user market. While all three players hold bargaining chips, the weight of those chips differs drastically in terms of substitutability, implementation costs, and strategic reach.

For Mongolia, transit rights offer direct leverage. In theory, Ulaanbaatar could exert influence through tariff hikes, regulatory red tape, or outright supply suspensions. However, tactical leverage does not equal strategic bargaining power. Mongolia’s economy is entirely wedded to Chinese mineral demand and Russian oil supplies. Unilaterally weaponizing its transit rights would not only forfeit transit revenues but invite devastating retaliation against its mineral trade and trigger a severe backlash from Moscow. Russia is equally constrained. Because of the inherent rigidity of pipeline infrastructure, once western Siberian gas is rerouted to China, Moscow cannot easily pivot to alternative buyers. A deliberate supply cut would yield nothing but a gaping revenue hole and stranded assets.

By contrast, China operates from a position of profound strength. It is the sole viable buyer for “Power of Baikai” the undisputed engine of Mongolia’s export economy, and the proud owner of a highly diversified energy matrix of domestic gas, Central Asian imports, and seaborne LNG. In this trilateral game, China—as the monopsony buyer with abundant alternatives—holds the ultimate negotiating advantage.

Ultimately, Mongolia’s geographic advantage cannot be readily cashed in for strategic dominance. As long as China rigorously defends its baseline of supply diversification, transit risks remain eminently manageable. Moving forward, the most realistic challenge will not be a dramatic, geopolitically motivated “gas shutoff,” but rather chronic, bureaucratic haggling over transit tariffs, taxation, and regulatory frameworks. Therefore, instead of indulging fears about Mongolia “closing the valve,” risk management should focus intensely on the drafting phase. By locking in rigid tariff mechanisms and severe breach-of-contract penalties through ironclad long-term agreements before ground is broken, Beijing can effectively neutralize future rent-seeking behavior and secure this vital energy artery under the strict confines of international law.
