<h1>President urges NATO and G7 to impose 50-100% tariffs on China and stop buying Russian oil</h1> The US president urged NATO and G7 allies to impose 50-100% tariffs on China and to stop buying Russian oil, and stated willingness to enact major sanctions on Russia once allied coordination is secured. The proposal seeks to use tariffs and secondary sanctions as geopolitical leverage to end the Ukraine conflict. Legally, coordinated high tariffs and extraterritorial sanctions raise potential challenges under WTO rules, national trade statutes, and limits on secondary sanctions; they also implicate allied treaty politics and enforcement mechanisms. Existing US-China tariff measures and prior tit-for-tat duties are noted as background.
