WASHINGTON — On Jan. 22, Donald Trump — just two days after being inaugurated for his second term as U.S. president — again called on Russian President Vladimir Putin to negotiate an end to the “ridiculous” war with Ukraine, but this time he added a threat. “If we don’t make a ‘deal,’ and soon, I have no other choice but to put high levels of Taxes, Tariffs, and Sanctions on anything being sold by Russia to the United States, and various other participating countries,” Trump wrote on his social media platform, Truth Social. The following day, Trump told reporters that Ukrainian President Volodymyr Zelenskyy had told him he’s ready to negotiate an end to the war. In an interview with Fox News aired that same day, Trump said Zelenskyy is “no angel” and “shouldn’t have allowed this war to happen.” Does the new U.S. administration have sufficient economic leverage over Russia to force it to make peace, or at least talk about peace?

There is an opportunity to strengthen secondary sanctions — that is, additional pressure, first of all, on China, on India, on other countries, so that they more strictly comply with the primary sanctions. “There is also an opportunity to continue what [former U.S. President Joe] Biden did with sanctions against the Russian shadow tanker fleet,” Sonin added, referring to vessels that Russia uses to sell oil and evade Western sanctions. “This requires great international cooperation, but, in principle, it can be done,” said Sonin. Economist Vladislav Inozemtsev, a special adviser to the Russian Media Studies Project at MEMRI, a Washington, D.C.-based think tank, and director of the Moscow-based Center for Post-Industrial Studies, also stressed the significance of secondary sanctions on countries that do business with Russia. “Trump can somehow influence other countries so that they do not buy Russian products,” Inozemtsev told VOA. “For example, let’s say he can … “Trump’s sanctions could force Russia’s Putin to negotiating table, some experts say” →
