US President Donald Trump has "greenlit" the bipartisan Russia Sanctions Bill, which could be used to penalise Moscow's trading partners, including India, China and Brazil, over their purchase of Russian oil, said Republican Senator Lindsey Graham, a prominent defence hawk. If passed, the Graham-Blumenthal sanctions bill would authorise the US President to levy up to 500 per cent tariffs on nations that knowingly purchase Russian oil or uranium and "fuel Russian President Vladimir Putin's war machine". The hard-hitting sanctions package is meant to economically cripple Moscow as the Trump administration continues to negotiate a deal to end the war that began with Russia's invasion of Ukraine.
