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.

The recent conflicts in Iran and Venezuela can be framed as a covert economic war against China. Since China buys 90% of Iran's oil and relies on Venezuela's supply, US actions disrupting these nations directly target China's energy security and serve as a tool of economic containment.

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.

Due to sanctions, Iran's oil exports go almost exclusively to China. This monopsony gives Beijing immense leverage, allowing it to demand deep price discounts and pay in yuan. The funds are held in Chinese banks, restricting Iran to using them only for Chinese goods, crippling its ability to buy essentials elsewhere.

Despite rhetoric about a new global axis, the China-Iran relationship is highly asymmetric. Iran sells over 80% of its crude to China, but this is only about 10% of China's supply. This dependency gives China leverage to remain uninvested in Iran's political survival, viewing it as a useful but disposable partner.

The move against Iran is not just a regional conflict but part of a grand strategy to disrupt the China-Russia-Iran-North Korea axis. By attempting to cut off China's access to cheap oil from Iran and Venezuela, the goal is to weaken China’s economic rise, even at the risk of global instability.

The US is disrupting China's oil supply from Iran and Venezuela (which accounts for ~20% of its imports) to gain a stronger negotiating position ahead of major talks. This frames the conflict as a geopolitical chess move rather than just a regional issue.

U.S. foreign policy actions against Venezuela and Iran are not primarily about democracy but are strategic moves to disrupt the flow of cheap, sanctioned oil to China. By controlling these sources, the U.S. can directly attack a key adversary's economic and military engine.

Since the U.S. is a net oil exporter, controlling massive reserves like Venezuela's is less critical. The real power now lies in controlling the flow of oil to adversaries like China, which is dependent on imports and could be crippled by a supply cutoff.
