A vast planned gas pipeline linking Russia’s Arctic energy fields to China is emerging as one of the most strategically significant infrastructure projects in global energy markets, underscoring the deepening alignment between Moscow and Beijing at a moment of shifting geopolitical pressure. The project, known as “Power of Siberia 2,” was discussed at a recent meeting between Russian President Vladimir Putin and Chinese President Xi Jinping, and is being closely tracked for its potential to reshape global gas flows over the coming decades, according to reporting by El País.
The proposed pipeline, stretching more than 2,600 kilometres, would connect Russia’s Yamal Peninsula—one of the world’s largest natural gas reserves—with major Chinese demand centres including Beijing and Shanghai. If completed, it would become one of the largest gas transport corridors in the world, reinforcing a structural energy partnership between Russia and China while reducing both countries’ exposure to Western energy markets and maritime liquefied natural gas (LNG) routes.
At its core, the project reflects diverging but complementary strategic needs. For China, the pipeline offers the possibility of securing large volumes of relatively low-cost natural gas delivered directly by land, potentially covering a significant share of its future consumption needs. For Russia, it represents a critical alternative export route after the collapse of most pipeline gas sales to Europe following the invasion of Ukraine, which has left its energy sector increasingly dependent on Asian buyers.
The infrastructure would extend and expand the existing Power of Siberia system, which has been operational since 2019 and currently delivers tens of billions of cubic metres of gas annually from eastern Russian fields into China. The planned second line is expected to dramatically increase capacity, potentially enabling combined flows that could supply a substantial portion of China’s total demand. Energy analysts cited in El País note that together, the two pipelines could eventually account for around one-fifth of China’s gas consumption, fundamentally embedding Russian supply into China’s long-term energy structure.
The project’s origins date back more than two decades, when early discussions between Moscow and Beijing first explored the idea of a transcontinental energy corridor. However, it is only in recent years—particularly following the deterioration of Russia’s energy relationship with Europe—that the concept has gained renewed urgency. With European markets largely closed to Russian pipeline gas, state-controlled energy giant Gazprom has come under increasing pressure to secure alternative buyers for its vast reserves, making the Chinese market central to Russia’s future export strategy.
Despite the apparent political momentum, key technical and commercial details remain unresolved. According to statements reported by El País, Russian officials have described a “shared understanding” with China regarding the route and general structure of the pipeline, but important aspects—including pricing mechanisms, financing arrangements and final investment decisions—are still under negotiation. China has not publicly confirmed specific commitments, reflecting the careful balance Beijing maintains in managing its energy diversification strategy.
The proposed route is expected to pass through Mongolia, linking Russian Arctic production zones with northern China before extending toward major industrial regions. While estimates vary, construction costs are widely expected to exceed €10bn, with some projections significantly higher depending on engineering complexity and geopolitical conditions. Even after approval, the timeline for completion is expected to stretch over several years of construction followed by gradual commissioning, meaning the pipeline would not reach full operational capacity until well into the next decade.
A key point of negotiation is pricing. Russian officials have indicated that the project may adopt a pricing formula similar to earlier long-term supply agreements with Europe, referencing past arrangements that were later disrupted by geopolitical conflict and sanctions. However, market conditions have shifted dramatically since then, with liquefied natural gas prices fluctuating in global markets and China gaining increased leverage due to its diversified import portfolio. Analysts suggest this could give Beijing greater bargaining power in securing favourable long-term terms.
The timing of the project reflects converging strategic pressures on both sides. Russia’s economy is increasingly reliant on energy exports to non-European markets, while China is seeking to reduce exposure to volatile seaborne LNG imports. Recent disruptions in global shipping routes, including tensions affecting key maritime chokepoints, have reinforced the attractiveness of overland supply routes that are less vulnerable to naval or geopolitical disruption.
If realised, the pipeline would significantly alter global LNG dynamics. By locking in long-term pipeline supply from Russia, China could reduce its reliance on spot-market LNG imports, freeing up global cargoes for other major consumers such as the European Union, Japan and India. This could have cascading effects on global pricing, shipping routes and investment decisions in LNG infrastructure worldwide.
However, the broader impact will not be immediate. Even in an optimistic scenario, analysts cited by El País suggest that it could take up to a decade before the pipeline reaches full operational capacity, including both construction and ramp-up phases. In the short term, global gas markets are unlikely to see major structural changes, but the long-term implications for supply security and geopolitical leverage are significant.
Beyond economics, the project also reflects a broader strategic alignment between Moscow and Beijing at a time of increasing global fragmentation. Energy infrastructure of this scale is typically designed for multi-decade operation, meaning that once completed, it would bind the two countries together through long-term contractual and physical interdependence. This could further consolidate a Eurasian energy axis less dependent on Western markets and financial systems.
Still, uncertainties remain. While political signalling from recent summits suggests momentum, the project’s scale, cost and complexity mean it is far from guaranteed. Financing, construction logistics across remote Arctic terrain, and long-term pricing agreements all remain potential obstacles. Moreover, shifts in global energy demand—particularly the long-term transition away from fossil fuels—could alter the economic assumptions underpinning the pipeline.
For now, however, “Power of Siberia 2” stands as one of the most consequential proposed energy infrastructure projects in the world. As reported by El País, it represents not only a potential reconfiguration of global gas flows, but also a deeper strategic alignment between China and Russia, with implications that could extend across energy markets, geopolitics and global trade for decades to come.
