Ukraine's President Volodymr Zelensky has accused Russia of "doing everything it can" to prevent a meeting with Vladimir Putin to try to end the war. US President Donald Trump has sought to bring the two leaders together, but he said on Friday "that's like oil and vinegar... they don't get along too well".

Doing so would require the Russian leader to “accept the failure of sitting down with a president he considers a joke from a country that doesn’t exist”

Analysts weighed in on what concessions Zelensky may consider making to end the war and what's likely to be off the table.
