刚刚签订的中俄超级大单，究竟有多重要？

Core Viewpoint - The article discusses the significance of the "Power of Siberia 2" gas pipeline project, highlighting its diplomatic and economic implications for China, Russia, and Mongolia, as well as the challenges faced in its long-term negotiation and construction [4][10][24]. Group 1: Project Overview - The "Power of Siberia 2" pipeline will transport 50 billion cubic meters of gas annually from Western Siberia through Mongolia to China, with a contract duration of 30 years [4][10]. - The project has been in discussion since 2015, with the recent signing of a memorandum marking a significant step forward after nearly a decade of delays [4][10]. Group 2: Route and Strategic Importance - The pipeline's route through Mongolia was chosen to enhance Russia's influence in the region and to provide Mongolia with a cleaner energy source, addressing its severe air pollution issues [9][10]. - The decision to avoid a route through Central Asia, despite competition from Kazakhstan, reflects strategic considerations for both Russia and China [9][10]. Group 3: Economic Implications - The project is expected to cost between $10 billion to $14 billion and will involve the construction of over 2,000 kilometers of pipeline [15][16]. - The pipeline's capacity is designed to match that of the now-destroyed "Nord Stream" pipeline, indicating its potential to significantly alter the energy supply landscape [15][22]. Group 4: Energy Demand and Supply Dynamics - China is projected to import 76.65 million tons of liquefied natural gas (LNG) in 2024, with a significant portion coming from pipeline gas, which is seen as more controllable and cost-effective [24][25]. - The reduction in gas exports from Central Asian countries like Kazakhstan and Uzbekistan has increased the urgency for China to secure more gas from Russia [25][26]. Group 5: Russia's Economic Context - Russia's gas exports to Europe have plummeted, with only 8.33 billion cubic meters sold in the first seven months of the year, leading to a critical need for alternative markets like China [26]. - The "Power of Siberia 2" project is seen as a necessary response to the declining European market, with the potential to supply approximately 106 billion cubic meters of gas annually to China [26].
