Moscow’s Energy Lifeline Now Belongs to Beijing

The clearest energy signal from Vladimir Putin’s May 20, 2026 meeting with Xi Jinping in Beijing was the deal the two leaders did not sign. China and Russia praised their partnership and signed more than 40 cooperation agreements. Putin called energy the “driving force” of the economic relationship. Yet the Power of Siberia 2 pipeline, which Moscow needs to make its post-Europe gas pivot credible at scale, remained unsigned.

The summit produced symbolism and paperwork. The missing pipeline breakthrough exposed the limit inside the choreography. Russia has escaped the clean isolation that Western governments hoped to impose after the full-scale invasion of Ukraine. Chinese demand has kept Russian oil, gas and coal moving, but the price of that escape is becoming clearer. Moscow has preserved a market by accepting a relationship in which Beijing can bargain over routes, discounts, finance and timing.

The paradox is stark: Russia has avoided energy isolation by accepting deeper dependence on China. The consequences now show up in prices, payment channels, pipeline talks and the leverage Beijing holds over a neighbour that used to sell much more of its energy to Europe on better terms.

The missing pipeline deal tells the story

For Russia, Power of Siberia 2 is the test of its post-Europe gas market. The proposed route would link the gas fields of northern Russia to China through Mongolia and give Gazprom a large eastern buyer after the collapse of its old European model.

The existing Power of Siberia pipeline has already changed the map. Gazprom says that line reached its design capacity of 38 bcm a year at the end of 2024. Because it draws from eastern Siberian fields, however, it does not recreate the old westbound business. Before the war, Russia could send far larger volumes to Europe through a network built over decades.

China wants Russian gas, but it also has Central Asian pipeline gas, liquefied natural gas, domestic coal, nuclear power, renewables and a policy of keeping many suppliers. China’s alternatives give Beijing what Moscow has lost. A handshake can signal alignment; a pipeline contract fixes price formulas, financing burdens, take-or-pay commitments and decades of bargaining power.

The summit’s lack of a final Power of Siberia 2 deal matters for that reason. The Kremlin said the sides had reached a general understanding, but the unresolved details are the substance. Russia needs the route to prove that Gazprom has a large market after Europe. China can wait.

Oil keeps Moscow liquid

Oil has done most to blunt Western pressure. Crude is easier to redirect than gas because tankers, traders and ports can be rearranged more quickly than pipeline systems. China became Russia’s largest crude customer because discounted barrels suited Chinese refiners and because Beijing refused to join Western sanctions.

The scale is no longer marginal. Chinese customs data cited by Reuters in January 2025 put Russian crude shipments to China at a record 108.5 million tonnes in 2024, about 2.17 million barrels a day. The U.S. Energy Information Administration’s May 2025 China brief put Russia at 20% of China’s crude imports in 2024, ahead of Saudi Arabia at 14%. The crude trade gives Moscow cash flow and gives Beijing a nearby supplier whose need to sell is greater than China’s need to buy any particular cargo.

The commercial names matter. PetroChina, Sinopec, CNOOC and Zhenhua Oil sit closer to Beijing’s political and sanctions calculations than an anonymous “Chinese buyer” does. Independent refiners in Shandong chase margins and discounted feedstock while banks and traders watch the compliance risk. On the Russian side, the pressure falls differently on Rosneft, Lukoil, Surgutneftegaz, Gazprom Neft, Transneft-linked routes, port operators, insurers and opaque shipping networks.

For the Kremlin, every barrel sold helps fund the state through company cash flow, taxes and export revenue. Oil and gas income still feeds the budget that pays soldiers, buys drones, replaces equipment and sustains occupied territories. Discounts shrink that pool without emptying it. For Chinese refiners, the same barrel is useful because it can arrive below the price of competing grades.

The price data make the imbalance explicit. In March 2026, analysts at the Gaidar Institute used Chinese customs data to estimate that Russian oil discounts to Chinese refiners cost Russian exporters $2.2 billion in 2025. China’s purchases of Russian crude fell to 91.4 million tonnes that year, while Russian export revenues from those sales dropped 20% to $45.9 billion. The trade continued under sanctions on worse terms for Russia.

Sanctions now work through friction

The Western sanctions campaign has produced friction. A clean embargo was always unlikely against one of the world’s largest commodity exporters, especially when China, India, Turkey and Gulf trading hubs were unwilling to enforce a Western line as their own. The sharper question is whether sanctions make Russian energy harder, slower or less profitable to sell.

The G7 and EU oil price-cap system was designed around that objective. Western shipowners, insurers and financial-service providers can handle Russian seaborne oil only if the cargo is sold at or below the cap. Russia answered by moving more trade through a shadow fleet and non-Western intermediaries. Ship-to-ship transfers, new insurance arrangements and greater tolerance for legal and environmental risk at sea became part of the workaround.

The enforcement contest became more specific in 2025. The EU’s 17th sanctions package, agreed in May 2025, targeted Surgutneftegaz and 189 shadow-fleet vessels. The package also reached shipping companies, insurers and actors in the United Arab Emirates, Turkey and Hong Kong. The Council of the EU said relevant Russian revenues had decreased by €38 billion since the bloc introduced the oil price cap and sanctions on the shadow fleet. The council put March 2025 revenues at 13.7% below March 2023 and 20.3% below March 2022.

The pressure then reached Chinese buyers. CREA’s February 2026 review of Russian fossil-fuel revenues said PetroChina, Sinopec, CNOOC and Zhenhua Oil paused purchases of Russian seaborne crude while assessing sanctions exposure. Seaborne crude sold by Lukoil and Rosneft to China fell from 3.6 million tonnes in September 2025 to none in January 2026.

Chinese firms stayed in the Russia trade while sanctions made even friendly buyers pause, reroute, demand larger discounts or shift risk to smaller intermediaries. The pressure is felt below the level of presidents: by bank compliance staff, tanker brokers, port officials, refinery managers and treasury officials deciding whether a shipment is worth the risk.

Gas exposes what Europe used to give

Gas makes Russia’s dependence more visible because it is less flexible than oil. Crude can move to Dalian, Qingdao, Ningbo or other ports if a buyer, tanker and payment route can be found. Pipeline gas needs fields, compressor stations, cross-border pipes, financing and long contracts.

Europe once gave Moscow leverage because geography and infrastructure made Russian gas hard to replace quickly. Nord Stream, Yamal-Europe, TurkStream and the Ukrainian transit system connected Russian supply to industrial consumers, households, utilities and governments across the continent. After 2022, Europe paid heavily to change that system. Nord Stream was disabled, EU demand for Russian pipeline gas collapsed from prewar levels, and Brussels moved from crisis substitution to long-term exit.

The first Power of Siberia line uses eastern fields, not the western Siberian base that served Europe. A second route would connect Russia’s old gas heartland to China, which is precisely why Beijing can demand favorable terms. Gazprom needs a replacement story more urgently than China needs a replacement supplier.

The politics are uncomfortable for Moscow. Gas used to be an instrument of Russian leverage over Europe. In the China relationship, Russian gas is becoming a request for Chinese commitment. Beijing can treat Russian gas as useful insurance against maritime disruption, Middle Eastern conflict and LNG price spikes. China does not need to treat the supply as a rescue mission for Gazprom.

Beijing buys leverage from the relationship

China’s support for Russia is rooted in interest more than sentiment. Beijing has rejected Western sanctions, increased trade with Moscow and provided diplomatic cover in a conflict where it presents itself as neutral while blaming the West for much of the confrontation. Beijing buys Russian energy because the economics and the geopolitics often suit Chinese interests.

Russia increasingly needs China as an outlet, a payments partner, a supplier of industrial goods and a diplomatic shield. China needs Russia less completely. The pause by PetroChina, Sinopec, CNOOC and Zhenhua Oil after sanctions on Russian oil companies shows what that imbalance looks like in practice: even friendly Chinese firms still checked whether a cargo, payment or counterparty had become too exposed.

The result is an unequal relationship. Russia brings resources, nuclear weapons and a willingness to challenge the West by force. China brings scale, finance, manufacturing and the decisive market for much of Russia’s redirected energy. In the transaction that matters most for Moscow, the customer has gained leverage over the seller.

The sanctions strategy is now about attrition

Western governments can make only a narrower claim for sanctions. The measures have yet to stop the war, cut off Moscow’s oil exports or force Beijing to abandon the Kremlin. Their effect is visible in the declining quality of Russia’s energy business. Western pressure has pushed more trade into discounted cargoes, longer routes, older tankers, opaque intermediaries and payment systems that large institutions approach carefully.

The attrition effect matters for Ukraine even if Ukraine needs more. A Russian budget receiving oil revenue at a discount can still finance salaries, drones, missiles, occupation administrations and replacement equipment. A refinery in China saving money on Russian crude does not see the cost paid in Ukrainian cities, Russian casualties or European defence budgets. The same energy flows that help Chinese refiners and Russian exporters also help the Kremlin sustain a war that Western policy is trying to make harder to fund.

For European governments and the United States, pressure works as attrition only when paired with enforcement, alternative supply, allied discipline and a clear view of what India, Turkey, Gulf traders and Chinese banks will actually do. Sanctions can make Russia poorer, more constrained and more dependent. Sanctions cannot reliably make China enforce Western strategy against China’s own interests.

The bargain now belongs to Beijing

A finalized Power of Siberia 2 agreement would change the balance only if China accepted terms generous enough to rescue part of Gazprom’s lost European business. Tighter tanker, insurer and bank enforcement would push in the other direction, letting China keep buying while Russia bears more of the cost.

For now, Russia has proved that Western sanctions cannot remove a major energy exporter from the world economy when China is willing to buy. China has proved something more useful to itself: it can turn Russia’s need into discounted oil, patient pipeline talks and a stronger hand in Eurasian politics. Russia has kept the fuel moving east. China increasingly decides what that movement is worth.
