September 02, 2025 [Reuters]- Russia agreed to supply additional volumes of natural gas to China and signed a memorandum on building the vast Power of Siberia 2 pipeline but has yet to agree on pricing for one of the world’s most expensive gas projects, Gazprom said on Tuesday.
The “no limits” partnership between China, the world’s biggest consumer of energy, and Russia, the world’s biggest producer of natural resources, has strengthened since the West imposed sanctions to punish Russia for the war in Ukraine.
Since losing a lucrative chunk of the European gas market, Russia has pivoted towards China, and Gazprom has sought an agreement for years on building the Power of Siberia 2 pipeline, capable of delivering 50 billion cubic metres (bcm) per year to China through Mongolia from the Arctic gas fields of Yamal.
Alexei Miller, the CEO of Gazprom, told Russian news agencies that an agreement had been reached to increase supplies via the existing Power of Siberia pipeline, which runs from Eastern Siberia to China, to 44 billion cubic metres (bcm) a year from 38 bcm.
“Today, a legally binding memorandum was signed on the construction of the Power of Siberia 2 gas pipeline and the Soyuz Vostok transit gas pipeline through Mongolia,” Miller said. Soyuz Vostok is designed to be the portion of the Power of Siberia 2 pipeline, traversing Mongolia.
But the price of gas supplied via the pipeline – one of the key factors for understanding the cost of building the pipeline and how those costs will be shared amongst the parties involved – will be agreed separately, Miller was quoted by the TASS state news agency as saying.
The price, Miller said, would be lower than the price charged by Gazprom to European buyers due to the vast distances and terrain over which pipelines had to be built.
It was also not clear who will build the pipeline. After President Vladimir Putin met Chinese President Xi Jinping and Mongolian President Ukhnaagiin Khurelsukh in Beijing, China’s state news agency Xinhua said bilateral deals were signed between Russia and China, including on energy, but did not mention Power of Siberia 2.
Building a gas pipeline from the vast Bovanenkovo and Kharasavey gas fields of northern Russia across the wilderness of Siberia to Mongolia and then to China would be the world’s biggest and most capital-intensive gas project, Miller said.
Reuters reported last month that China was seeking to buy more Russian gas through an existing pipeline as talks between the two countries had failed to make significant progress on building a new link.
Gazprom shares edged up 0.5% in Moscow trading.
CHINA BUYING
Putin and Xi, who have both pushed back against the perceived humiliations of the 1991 collapse of the Soviet Union and centuries of European colonial dominance of China, say the world is entering a new era with the West in decline.
The United States casts China as its biggest competitor and Russia as its biggest nation-state threat, though U.S. President Donald Trump has criticised Western moves he thinks have pushed Moscow and Beijing closer.
China is now Russia’s biggest trading partner, the biggest purchaser of Russian crude and Russian gas, the second-biggest purchaser of Russian coal and the third-biggest purchaser of Russian LNG, according to the Kremlin.
Gazprom supplies natural gas to China through a 3,000 km (1,865 mile) pipeline called Power of Siberia under a 30-year, $400 billion deal launched at the end of 2019.
In 2024, exports amounted to about 31 billion cubic meters (bcm). It is expected that supplies will reach the planned capacity of 38 bcm this year.
In February 2022, China also agreed to buy up to 10 bcm of gas annually by around 2026-2027 via a pipeline from Sakhalin Island in Russia’s Far East.
Miller said an agreement had been reached to increase gas supplies via the Far Eastern route to 12 bcm from the 10 bcm.
But Russia’s gas exports to China are still a small fraction of the record 177 bcm it delivered to Europe in 2018-19 annually.
Russian gas now accounts for just 18% of European imports, down from 45% in 2021, while the bloc’s oil imports from Russia have fallen to 3% from around 30% over that time. The European Union plans to fully phase out Russian energy by 2027.
