Ukrainian President Volodymyr Zelenskyy said Thursday that Kyiv is “geared up for clear and honest work” to develop a peace plan to end the country’s war with Russia, after being presented with draft proposals by U.S. delegates.

On Tuesday, Axios reported that a secret peace deal was being drawn up by Washington and Moscow, with some media outlets reporting a breakthrough could be imminent.

In a post on the social networking site Telegram, Zelenskyy said he had met with a high-level U.S. delegation on Thursday and engaged in “a very serious conversation.”

“The American side presented its proposals — the points of a plan to end the war — their vision,” he said.

The 28-point peace plan drawn up by the U.S. and Russia is reported to include proposals for Ukraine to give up territory in its eastern Donbas region and halve its armed forces, among other conditions.
