Ukrainian President Volodymyr Zelenskyy said the latest version of a plan to end the Russian invasion would freeze the front line, but still pave the way for Ukrainian withdrawals and the creation of demilitarized zones.

Zelenskyy said the 20-point plan, agreed on by U.S. and Ukrainian negotiators, was being reviewed by Moscow. The Kremlin is unlikely to abandon its hard-line territorial demands and Zelenskyy also conceded there are some points in the document that he does not like.

But it appears Kyiv has managed to shift the plan away from an original 28-point U.S. proposal, which adhered to many of Russia’s core demands.

That plan had demanded that Ukraine withdraw from the 20% of the Donetsk region it still controls and that land occupied by Moscow be recognized as Russian territory.

A requirement for Kyiv to legally renounce its bid to join NATO has also been dropped from the latest plan, though the United States has long said it would not admit Ukraine to the bloc.

“In the Donetsk, Lugansk, Zaporizhzhia, and Kherson regions, the line of troop deployment as of the date of this agreement is de facto recognized as the line of contact,” Zelenskyy said of the latest version.

“A working group will convene to determine the redeployment of forces necessary to end the conflict, as well as to define the parameters of potential future special economic zones,” he added.

Zelenskyy shared details of the 20-point plan with journalists in a briefing in Kyiv on Tuesday, published early Wednesday morning.

This appears to suggest the plan opens the way for, but delays, options that Ukraine was previously reluctant to consider — a withdrawal of troops and the creation of demilitarized zones.

“We are in a situation where the Russians want us to withdraw from the Donetsk region, while the Americans are trying to find a way,” Zelenskyy said.

“They are looking for a demilitarized zone or a free economic zone, meaning a format that could satisfy both sides,” he continued.

Ukraine also suggested Energodar, a city occupied by Russia that manages the Zaporizhzhia power plant, could become a demilitarized zone.

Any plan that involves Ukraine pulling back its troops would need to pass a referendum in Ukraine, Zelenskyy said.

“A free economic zone. If we are discussing this, then we need to go to a referendum,” Zelenskyy said.

The plan also sees joint U.S.-Ukrainian-Russian management of the Zaporizhzhia plant, occupied by Russian troops. Zelenskyy said he does not want any Russian oversight of the facility.

He also said Ukraine would hold presidential elections only after an agreement is signed.
