How Donald Trump is leveraging the U.S. economy to use purchases of Russian oil by China and India to damage Russia's war effort.

Indian experts believe the U.S. president is trying to gain short-term leverage in trade negotiations with New Delhi.

Russian oil exporters are predicted to take in $153 billion this year, according to the Kyiv institute. Fossil fuels are the single largest source of budget revenue. The imports support Russia’s ruble currency and help Russia to buy goods from other countries, including weapons and parts for them.
