<h1>Two governments restart reciprocal trade measures, new export controls and tariffs spark supply-chain disruption and legal risks</h1> Two governments have resumed reciprocal trade measures-new export restrictions on critical minerals, threats of sweeping import tariffs and tighter export controls, and increased port fees-after a period of de-escalation, reviving market volatility and supply-chain disruption. The measures raise immediate legal and regulatory risks including broader tariff exposure, export-control compliance burdens for firms, potential WTO dispute claims, and contractual performance issues for exporters and importers. Ongoing uncertainty whether actions are bargaining tactics or durable policy increases litigation and transactional risk and complicates prospective negotiations scheduled at an upcoming multilateral summit.
