China is aware of its commercial interests and has reportedly pressured Iran to curb the Houthi blockade. But its diplomatic efforts have lacked determination. Beijing and Moscow opportunistically cut deals with the Houthis to allow transit of their vessels – although the agreement has not prevented missile attacks on Russia-to-China shipments, including a recent incident in mid-July. While Beijing does not have unlimited leverage over either Tehran or Moscow, it can do more to solve the multiple crises engulfing the region.
Russia has threatened to extend its involvement in the Red Sea crisis, as Moscow aimed to deliver weapons to the Houthis but withdrew amid pressure from Washington and Riyadh. Still, unconfirmed reports hold that Russian GRU military intelligence officers are on the ground in Yemen.
Beijing can privately urge Moscow not to step up its involvement in the Red Sea crisis, particularly since the entanglement poses escalation risks.
But China is better able to mitigate Gulf instability by insisting that Iran de-escalate in the Red Sea and with Israel.
Beijing has far more capacity to exert influence on Tehran. China is Iran’s largest trading partner, by far. Not only is China the world’s sponge for Iranian crude oil exports, soaking up 90 per cent of all these shipments, but Iran is awash in Chinese imports.
Beijing could privately warn Tehran that Chinese exports to Iran would come under pressure with a further escalation in conflict in the Middle East. A reduction in Chinese imports would accelerate Iran’s inflation, which already stands at an eye-watering 37 per cent.
Perhaps more importantly, Beijing could hint that unconstructive behaviour from Tehran could lead it to unwind purchases of Iranian crude oil. This course of action would be credible. Oil prices have trended downwards in recent months, world spare oil production capacity stands at a historically high 5.8 million barrels per day, and other producers would welcome the opportunity to increase market share at Tehran’s expense.
While Iran is not the only regional actor that must be restrained, its behaviour is increasingly aggressive and destructive. Beijing is uniquely positioned to hold back Tehran. If it fails, the region should take notice.
