Russia's interests are served by an isolated Iran that doesn't compete in European gas markets or its Central Asian sphere of influence. In contrast, China would gain from a stable, economically powerful Iran that can maximize its energy output and open its large market to global commerce.
While Venezuela is a minor oil supplier to China, Iran is a substantial source of crude and heavy oil used for infrastructure projects like asphalt. A regime change in Iran could lead to the country selling its oil to the West instead of China, creating a significant economic and geopolitical destabilization for Beijing.
Historically, Russia and China's strategy as continental empires involves avoiding two-front wars and actively destabilizing neighboring states. This creates buffer zones and prevents any single power from becoming a threat on their borders, ensuring their own security through regional instability.
China's renewed commitment to the previously stalled Power of Siberia 2 gas pipeline is a direct geopolitical response to the U.S. using trade and energy as weapons. This move signals a strategic pivot to reduce its energy dependency on the Western Hemisphere amid escalating trade tensions.
While China gains access to resources, its de facto alliance with Russia is a long-term liability. It damages relations with Europe and risks entanglement in conflicts where China has little interest, driven by Russia's own quarrels and irresponsible international behavior.
China's investment in green technology is driven less by environmentalism and more by strategic goals. By dominating renewables and EVs, China reduces its dependence on foreign oil—a key vulnerability in a potential conflict with the US—while building global soft power and boosting its GDP through green tech exports.
Protests in Iran, if they disrupt the regime, could halt cheap oil flows to China. This would force China to buy from more expensive, US-friendly markets, strengthening the US dollar's global dominance and isolating anti-Western powers without direct US intervention.
While Venezuela was a key oil supplier and geopolitical asset, it was also seen as a failed investment ("money gone to waste"). Iran, by contrast, is a core strategic partner in China's "axis of ill will" against U.S. influence. A regime collapse in Iran would be a far more significant blow to China's global strategy.
Throughout the 19th and 20th centuries, Russia consistently manipulated China during its moments of weakness. It offered "mediation" in conflicts like the Opium Wars that ultimately served Russian interests by keeping China destabilized and forcing it to cede territory.
In Russia, nominally private companies like Gazprom function as direct extensions of the state. Their international investments are designed not just for profit but to achieve geopolitical goals, creating a system where foreign policy, business interests, and the personal wealth of the ruling class are completely inseparable.
The current Iranian protests are uniquely potent because the regime is at its weakest geopolitically. The loss of regional proxies like Hezbollah and Hamas, coupled with key ally Russia's preoccupation with Ukraine, has left the Iranian government more isolated and vulnerable than during any previous wave of unrest.
