How China Became Russias Economic Lifeline

China has become Russia's primary economic lifeline post-Ukraine invasion, absorbing massive volumes of crude oil, coal, and natural gas, providing hard currency despite Western sanctions. In return, China supplies machinery, electronics, and critical technology inputs, mitigating Russia's technology import restrictions. The shift to ruble-yuan settlement reduces USD dependency. This creates a dual-channel commercial mechanism: (1) sustained demand for Russian energy commodities supports global oil/gas prices at the margin, and (2) China's role as a technology supplier to Russia may expose Chinese firms to secondary sanctions risk, affecting their compliance costs and access to Western markets. The impact is global for energy markets and EM-specific for Russia-China trade flows.
