China reportedly presses Iran to help rein in the Houthis after Saudi appeal, according to Reuters citing sources

China has been the primary buyer of Iranian crude and the broker of the Iran-Saudi normalisation, so it is one of the few actors with real leverage over both parties, and Riyadh's involvement reflects its prior form of seeking de-escalation with Iran since their rapprochement. Episodes where Iran has been pressed to restrain proxies have tended to produce partial, temporary compliance rather than durable cessation, with attacks pausing and resuming as leverage is reasserted. For crude, the transmission runs through Red Sea transit: freight rates, insurance premia, and rerouting around the Cape, with any credible Houthi de-escalation historically unwinding the war-risk premium embedded in tanker costs and, to a lesser extent, the flat price. The distinction worth drawing is between a rhetorical commitment and verified restraint; the tells are the actual cadence of attacks on shipping and whether carriers resume Suez transits. Watch for confirmation from Iranian or Houthi channels, which have on past occasions contradicted such diplomatic accounts within days.
