Ukraine provided the Trump administration with a detailed, point-by-point response to the latest draft of the U.S. 20-point peace plan on Wednesday.

The plan, which includes significant territorial concessions, has put pressure on Ukrainian President Volodymyr Zelensky to act quickly.

Zelensky’s adviser Rustem Umerov sent the response to Jared Kushner after consultations with European allies, including France, Germany, and the U.K., proposing amendments to make the plan more workable.

Key sticking points addressed include territorial issues and the Zaporizhzhia nuclear power plant, Axios has reported.

U.S. and Ukrainian military officials are scheduled to hold a virtual meeting Thursday to continue discussions on the plan.
