This opinion was expressed on the air of Espreso by journalist Vitaly Portnikov."Donald Trump can impose a tariff on any product that Russia supplies to the U.S. Will this somehow affect the Russian economy? Trade volumes between the U.S. and Russia have grown to insignificant figures. However, these are not the figures that will affect the Russian economy. It is worth adding that all these trade volumes between the U.S. and Russia are maintained only because Moscow supplies products that are needed by the American economy. And that is why the U.S. did not refuse this trade. I think that there will be no real results if we do not introduce a 100% tariff on Russian products," Portnikov explained.According to the journalist, for China, the purchase of Russian energy resources has not only economic but also political significance. Beijing sees Russia as a proxy force to weaken the West."There is a more serious factor that could affect the Russian economy. In particular, trade related to the Russian energy sector. Sanctions against Russia's partners who purchase Russian oil. By the way, I believe that Trump reduced the number of days for Putin after he held successful negotiations with the head of the European Commission, Ursula von der Leyen. Then they agreed that the EU would finally abandon Russian energy resources. This is really beneficial for Trump, because he is actually limiting the supply of Russian oil to the European market and can replace these energy resources with American supplies. Then Trump can talk about other recipients of Russian oil. The main meaning of the Russian budget in terms of energy resources is created by India and China. The situation with China is clear and they will not reduce the volume of purchases of Russian oil. For China, the purchase of Russian oil has not only economic, but also political significance. They buy Russian oil because they want to support Russia as their own proxy force in weakening the West," he added.On July 14, Donald Trump announced that he would impose secondary tariffs on Russia, which could reach 100%, if a peace agreement with Ukraine is not reached within 50 days.In turn, the deputy chairman of Russia's Security Council and former Russian President Dmitry Medvedev called Trump's statement about a 50-day deadline for Russia a "decorative ultimatum."On July 29, the President of the United States announced that he had reduced the deadline for Russian leader Vladimir Putin to demand a ceasefire in Ukraine to 10 days.On July 31, it became known that U.S. President Donald Trump wants an agreement to end Russia's war against Ukraine to be concluded by August 8.
