Why the Iran War is Forcing China to Rethink Putin's Stalled Gas Pipeline

Vladimir Putin just landed in Beijing with a massive 39-man delegation, five deputy prime ministers, and a desperate need to sell some gas. For years, the Russian president has tried to bully and cajole Xi Jinping into signing off on the Power of Siberia 2 pipeline. This 2,600-kilometer mega-project is designed to pump 50 billion cubic meters of natural gas annually from the Arctic Yamal peninsula straight into China through Mongolia.

Until recently, Beijing didn't really care about Moscow's timeline. China held all the cards, dragging out negotiations while demanding absurdly low, heavily subsidized domestic Russian prices.

But geopolitics moves fast. The outbreak of the US-Israeli war on Iran has effectively turned the global energy market upside down. With the Strait of Hormuz largely closed, a chokepoint responsible for a third of China's oil and a quarter of its liquefied natural gas (LNG) imports has vanished. Suddenly, land-based energy routes don't look like an expensive luxury anymore. They look like a survival mechanism.


The Strait of Hormuz Trapping Beijing

Look at the math. China consumed roughly 456 billion cubic meters of gas in 2025. Demand isn't slowing down, either; it's on track to peak around 610 billion cubic meters by 2040. To fuel this growth, Beijing relied heavily on seaborne LNG from Middle Eastern giants like Qatar, alongside shipments from Australia.

The war in Iran changed everything. Maritime shipping routes are no longer safe or guaranteed. When the Strait of Hormuz closed, Chinese policymakers realized their coastal regasification terminals were highly vulnerable to blockades and regional warfare. If U.S.-China tensions over Taiwan flare up, those maritime supply lines from Australia and the Gulf could be cut in a heartbeat.

That's why Beijing's latest five-year plan, approved in March, explicitly called to "advance preparatory work" on this central pipeline route. It's not a coincidence. The war in the Gulf is driving China right into Putin's arms, even if Xi Jinping hates the idea of depending too much on a single volatile neighbor.


Why Putin Needs This Deal Yesterday

Let's not twist the reality here: Russia is still the desperate party in this relationship. Four years after the full-scale invasion of Ukraine, Moscow's economic troubles are mounting. The European market, which used to be state-owned Gazprom's ultimate cash cow, is gone for good.

Existing vs. Proposed Russian Gas Capacity to China:
- Power of Siberia 1: ~40 billion cubic meters (2025 actuals)
- Power of Siberia 2: 50 billion cubic meters (Proposed capacity)

Russia managed to send nearly 40 billion cubic meters of gas through the original Power of Siberia 1 pipeline last year, but it's not enough to balance the books. Gazprom needs the Power of Siberia 2 to recycle the massive reserves of the Yamal Peninsula—the very fields that used to supply Germany and France.

Putin has openly admitted he wants a deal locked down, stating that both nations are close to a "very substantial step forward." Gazprom has reportedly offered incredibly competitive pricing. But offering cheap gas to China is like bringing a knife to a gunfight; Beijing always wants more for less.


The Real Stumbling Blocks Nobody Talks About

If the strategic logic is so flawless, why hasn't anyone signed the contract? It comes down to cold, hard cash and control.

First, there's the price tag. China wants to pay something close to Russia's heavily subsidized domestic gas rate. Moscow can't afford to sell its resources at a loss, especially when funding a prolonged war effort.

Second, China refuses to commit to the full 50 billion cubic meter capacity. Beijing wants a flexible arrangement where they only take 50% of that volume, leaving the rest as an optional backup. They don't want to become overly reliant on Moscow, especially since they've spent the last decade diversifying their land supply via Line D from Turkmenistan and expanding routes from Central Asia.

Then there's the timeline problem. Even if Xi and Putin share a ceremonial tea in Beijing and sign a final contract today, you won't see gas flowing next month. Industry reality dictates that building a 2,600-kilometer pipeline across the rugged terrain of Mongolia takes at least five years. Reaching full capacity takes another five. Energy experts at S&P Global don't expect this pipeline to be fully operational until 2031.


What Happens Next

Don't buy into the hyperbole that a signed memorandum means the deal is done. We saw Gazprom sign a "legally binding" memorandum in September 2025, yet here we are, still watching both sides haggle over the fine print.

If you want to understand where global energy security is heading, watch the pricing compromises over the next few months. If Moscow swallows its pride and accepts Beijing's low-ball pricing in exchange for China footing the bill for Mongolian transit construction, the project moves forward.

For corporate energy buyers and geopolitical strategists, the move is clear: stop treating Russian land-based pipelines as an impossibility. Begin pricing in a long-term Eurasian energy bloc that operates entirely outside Western banking systems and maritime chokepoints. Diversify away from spot-market LNG contracts that rely on the Middle East, because overland supply integration between Russia and China is no longer a question of "if," but "when."
