<h1>China rejects G7 proposal for tariffs or sanctions on Russian oil importers, warns of extraterritorial legal risks</h1> China's foreign ministry rejected a US-led proposal for G7-imposed tariffs or sanctions on countries importing Russian oil, arguing that sanctions complicate disputes and urging resolution through dialogue. The development highlights tensions over use of unilateral or coalition trade measures to influence third countries' energy purchases and raises issues under international trade and sanctions law, including extraterritorial effect, jurisdictional reach, and treaty obligations among G7 members and targeted states. Potential legal consequences include trade disputes, retaliatory measures, and challenges to enforcement and coordination of multilateral coercive economic measures.
