United States President Donald Trump has stated that he will not meet with Russian President Vladimir Putin until there is a clear agreement on ending the conflict in Ukraine. Trump expressed disappointment over the lack of progress, noting that he expected a resolution sooner. Despite the collapse of summit plans, discussions between Russian and United States officials continue, with some optimism from the Russian side about nearing a diplomatic solution. Meanwhile, new sanctions have been imposed by the United States and the European Union on Russia's oil sector, which Putin acknowledged as serious but not crippling.
