"Western sanctions have cleared the Russian market for the Chinese and forced Russian exporters of raw materials to rush to China" [Western sanctions]
This quote directly names the sanctions mechanism as the causal driver converting Russia into a captive supplier and consumer, which is the core structural claim about how isolation creates dependency and leverage asymmetry.
Reasoning from this article
The article treats Russia's case as an instance of a general dynamic: when a major power is cut off from its primary markets by sanctions, its remaining trade partner gains structural leverage that compounds over time. The same logic applies to any heavily sanctioned commodity exporter with limited alternative buyers — the sanctioning coalition inadvertently concentrates the target's economic relationships, empowering the one large partner willing to trade. Russia's inability to advance Power of Siberia 2 on favorable terms, and China's insistence on domestic-rate gas pricing, are downstream symptoms of this structural shift rather than isolated negotiating outcomes.
