<h1>China and US roll back extreme tariffs and export controls, easing trade confrontation; supply-chain instability and green-tech protectionism remain unresolved</h1> Chinese and US leaders reached bilateral agreements to roll back extreme tariff and export-control measures, easing an immediate trade confrontation while the Chinese leader urged multilateralism and supply-chain stability at the regional economic forum attended by 21 economies. The US leader's absence from the summit underscores tensions over multilateral engagement; host authorities sought a consensus communique but warned differing member positions may preclude a strong free-trade endorsement. The developments reduce near-term legal risks from tariff escalation and export controls but leave unresolved legal and regulatory challenges around protectionism, green-tech trade practices, supply-chain decoupling and harmonisation of standards.
