The next step of the diplomatic process aimed at putting an end to Russia’s war against Ukraine is set to be a meeting between Volodymyr Zelenskyy and Vladimir Putin. But where could that meeting take place?

The denial of a Putin-Zelenskyy meeting comes days after Donald Trump said he had begun arrangements for them to sit down together.

Trump sounded positive on Monday as he met with Ukrainian President Volodymyr Zelenskyy and European leaders at the White House, just two days after his summit with Russia's Vladimir Putin in Alaska. "I think President Putin will make peace. I think President Zelensky will make peace. We'll see if they can get along," Trump said.
