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.

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.

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.

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.

The US is moving from a global deterrence posture to concentrating massive force for specific operations, as seen with Iran. This strategy denudes other theaters of critical assets, creating windows of opportunity for adversaries like China while allies are left exposed.

Beijing interprets America's focus on regions like Latin America or the Middle East with a 'shoulder shrug.' They see these distractions as beneficial, giving them more freedom to aggressively pursue their own interests and push allies in the Indo-Pacific without US interference.

By forcing the U.S. to operate its air defense systems at scale, the conflict in Iran is inadvertently providing China with a treasure trove of intelligence. The Chinese can observe how these systems perform, identify weaknesses, and refine their own tactics for a potential future conflict.

China plays the long game. Instead of direct confrontation, its strategy is to wait for the U.S. to weaken itself through expensive military interventions and political division. This allows China to gain relative power without firing a shot, similar to its rise during the War on Terror.

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.
