U.S. President Donald Trump has indicated that Washington may reinstate sanctions-related waivers on Russian oil exports. Speaking to reporters in Paris, Trump said he could "put them back on" after previously easing restrictions to help keep global oil prices low. He noted that crude prices have since declined significantly, opening the door for a policy rethink. Trump also claimed Ukraine is "doing pretty well" on the battlefield and reiterated that European allies and NATO are paying for military equipment supplied to Kyiv. The remarks come after a key U.S. sanctions waiver on Russian seaborne oil expired this week.
