紧系石油，俄罗斯向中国设下了一道考验

Group 1 - The core of Sino-Russian oil cooperation began in the late 1990s, with Yukos Oil Company emerging as a significant player in Russia's oil industry under Mikhail Khodorkovsky's leadership [1][3] - Khodorkovsky's arrest in October 2003 led to a collapse in Yukos's stock and disrupted major pipeline projects, prompting the Russian government to shift its strategy towards the Taishet-Nakhodka pipeline [3][6] - The initial agreement for the Angarsk-Daqing pipeline was signed in 2003, aiming to supply China with oil amidst its growing energy demands, but was ultimately abandoned due to Yukos's instability [4][6] Group 2 - The Russian government’s decision to prioritize its own interests over Sino-Russian cooperation was evident when it sidelined Yukos and strengthened state control over the energy sector [6][8] - The construction of the East Siberia-Pacific Ocean (ESPO) pipeline continued despite Yukos's downfall, with the first phase completed in 2009 and the second phase in 2012, allowing for significant oil exports to China [8][9] - By 2023, Sino-Russian trade had increased significantly, reaching $240 billion, with oil being a major component, as China imported over 100 million tons of crude oil from Russia [9][11] Group 3 - The geopolitical landscape shifted in 2025, with new sanctions from the US and EU affecting Russian oil exports, leading to a decrease in China's imports of Russian oil [11][12] - Despite challenges, the relationship between China and Russia has strengthened, with China providing loans in exchange for oil, thus securing its energy resources while helping Russia navigate sanctions [11][12] - The complexities of the Sino-Russian energy relationship highlight vulnerabilities, as both countries adapt to external pressures and seek to diversify their energy strategies [12]
