China Is Playing the Long Game over Iran

China is maintaining a cautious diplomatic stance toward Iran despite a 25‑year strategic partnership and its role as Tehran’s primary oil buyer, accounting for over 80% of Iranian exports in 2025. Beijing publicly urges restraint and dialogue while opposing Iran’s pursuit of nuclear weapons, fearing regional escalation that could threaten vital shipping lanes. The restraint is not a sign of unreliability but a long‑term strategy to deepen economic dependence and gain leverage as U.S. pressure on Tehran intensifies. China’s approach blends energy security, geopolitical calculus, and a bid to shape the Middle‑East balance of power.
