Russian President Vladimir Putin failed to secure agreement on a proposed gas pipeline to China during talks with Chinese leader Xi Jinping this week, according to Ukrainian sources cited by Ukrainska Pravda, highlighting Beijing's reluctance to deepen energy dependence on Moscow despite their proclaimed "no limits" partnership.The proposed Power of Siberia 2 pipeline, which would transit through Mongolia to deliver an additional 50 billion cubic meters of Russian gas annually to Chinese markets, has been under negotiation for more than two years. China's hesitation to finalize the deal reflects growing concerns about price, geopolitical risk, and over-reliance on Russian energy as Western sanctions continue to constrain Moscow's options.To understand today's headlines, we must look at yesterday's decisions. When Russia's invasion of Ukraine prompted sweeping Western sanctions and the effective closure of European markets, Moscow pivoted aggressively toward Asia. The existing Power of Siberia 1 pipeline, operational since 2019, already supplies Chinese markets. But Russia needs additional export routes to offset the collapse of its European gas business, which once accounted for more than 40 percent of Gazprom's revenue.China, however, has proven to be a shrewd negotiator. According to energy analysts familiar with the discussions, Beijing has demanded significant price concessions and is insisting on terms that would give Chinese state companies substantial control over the project's commercial arrangements. Xi's government is also wary of appearing to underwrite Russia's war effort through major energy commitments that could trigger secondary Western sanctions on Chinese entities."China wants Russian gas, but on its terms and at its price," said Alexander Gabuev, director of the Carnegie Russia Eurasia Center, in recent commentary. "Putin needs this deal far more than Xi does, and Beijing knows it.". European markets that once consumed the bulk of Russian gas exports have successfully diversified to liquefied natural gas from the , , and other suppliers. Russia's oil revenue, while still substantial, has been constrained by price caps and the growing costs of maintaining shadow tanker fleets to circumvent sanctions.Ukrainian sources, while clearly invested in portraying Russian setbacks, noted that the lack of agreement during this week's talks represents a significant diplomatic failure for , who has repeatedly touted the Russia-China relationship as a counterweight to Western isolation. The Kremlin has not officially commented on the pipeline negotiations, though Russian state media have downplayed the significance of any disagreement.For , which would host the pipeline's transit route and collect substantial fees, the delay is a disappointment. has been navigating a delicate balance between its two giant neighbors, seeking economic benefits without antagonizing either or .Energy analysts suggest that while an agreement may eventually be reached, the terms are likely to be far less favorable to Russia than Moscow initially hoped. China's strengthening negotiating position reflects the broader reality that Russia's strategic options have narrowed considerably, even as it seeks to portray deepening ties with as evidence of its resilience in the face of Western pressure.
