The US Senate has passed a sanctions bill on Russia that could give President Donald Trump the authority to impose 100 percent tariffs on the top five buyers of Russian oil, including India and China, if the legislation becomes law.Against this backdrop, Indian Congress leader and MP Pawan Khera launched a sharp attack on the Modi government, asking in Prayagraj whether India is truly independent.“Is India really independent?” Khera asked journalists, alleging that foreign powers were blackmailing India and dictating how much oil the country can buy and from whom.He said those who call themselves “Vishwaguru” should answer these questions, but accused them of lacking the courage to face such issues in Parliament.“They are afraid to be accountable to the people,” Khera said.The bill passed by the US Senate reportedly targets countries involved in buying Russian oil and gas, with the possibility of tariffs or sanctions of up to 100 percent. The development has once again put India’s foreign policy and the government’s stance under scrutiny, with the Congress putting the Centre on the defensive over the issue.
