The path ahead for Ukraine peace talks is unclear, U.S. President Donald Trump said on Wednesday, after what he called "reasonably good" talks between Russian President Vladimir Putin and U.S. envoys.

The Kremlin said on Wednesday that Putin accepted some U.S. proposals aimed at ending the conflict in Ukraine and was prepared to keep working to find a compromise.

U.S. special envoy Steve Witkoff and Trump advisor and son-in-law Jared Kushner spent hours at the Kremlin, departing in the early hours of Wednesday morning with no specific breakthrough on ending the conflict. The two U.S. envoys would meet with Ukrainian officials in Miami on Thursday. 

Trump, speaking to reporters in the Oval Office, said Witkoff and Kushner briefed him about the talks via telephone and told him their impression from Putin was that "he would like to make a deal." What happens now, however, is unclear, Trump said.

"What comes out of that meeting I can't tell you because it does take two to tango," Trump said, without elaborating. He added: "We have something pretty well worked out (with Ukraine)."

Russian presidential aide Yuri Ushakov said on Wednesday that Putin and Witkoff discussed Ukraine's accession to NATO during their talks.

Kremlin spokesman Dmitry Peskov, asked if it would be correct to say that Putin had rejected the U.S. proposals, disagreed.

"A direct exchange of views took place yesterday for the first time," Peskov said. "Some things were accepted, some things were marked as unacceptable. This is a normal working process of finding a compromise."

Peskov said Russia was grateful to Trump for his efforts but the Kremlin would not be giving a running commentary on discussions with the U.S., as publicity was unlikely to be constructive.

"Work is currently being carried out at a working expert level," Peskov said. "It is at the expert level that certain results should be achieved that will then become the basis for contacts at the highest level."

Ukrainian President Volodymyr Zelenskyy said in his nightly video address that his team is preparing for meetings in the United States and that the dialogue with Trump's representatives will continue.

"Only by taking Ukraine's interests into account is a dignified peace possible," Zelenskyy said.

A leaked set of 28 U.S. draft peace proposals emerged in November, alarming Ukrainian and European officials who said they bowed to Moscow's main demands.

European powers then came up with a counter-proposal, and at talks in Geneva, the U.S. and Ukraine said they had created an updated and refined peace framework to end the conflict.

Putin on Tuesday said European powers were trying to sink the peace talks by proposing ideas which were absolutely unacceptable to Russia.
