MOSCOW/WASHINGTON - Russia is "in favor" of the 30-day ceasefire plan proposed by the United States and Ukraine, but nuances exist, Russian President Vladimir Putin said Thursday.

"We agree with the proposals to stop hostilities, but we proceed from the fact that this cessation should be one that would lead to long-term peace and eliminate the original causes of this crisis," Putin said at a press conference with visiting Belarusian President Alexander Lukashenko.

Putin noted the difficulty in monitoring ceasefire violations along the 2,000 km contact line of the conflict and raised the issue that Ukraine might use the temporary ceasefire for mobilization and weapons supplies.

He mentioned the nuance regarding the Kursk region, where Russian forces have been pushing back Ukrainian forces following their surprise cross-border attack in August 2024.

"As for the situation on the ground..., it is changing rapidly," Putin said, noting Russian forces' recapture of the key town of Sudzha in Kursk on Thursday. Kremlin spokesman Dmitry Peskov said earlier in the day that the Russian operation in Kursk had entered its final stage.

Putin said he might call US President Donald Trump to discuss the issues.

Russia will negotiate the next steps to end the conflict and reach acceptable agreements based on the situation "on the ground," the president said.

Ukraine on Tuesday signaled its readiness to accept a US proposal for an "immediate, interim 30-day ceasefire" following talks with a US delegation in Jeddah, according to their joint statement.

The statement also said the truce could be extended by mutual agreement, adding that "the United States will communicate to Russia that Russian reciprocity is the key to achieving peace."

'Good signals' on ceasefire plan

Trump said on Thursday that he saw "good signals" toward finalizing a 30-day ceasefire agreement between Russia and Ukraine.

While meeting with NATO Secretary General Mark Rutte at the White House, Trump offered guarded optimism when he was asked by reporters about Putin's statement earlier in the day.

"He (Putin) put out a very promising statement but it wasn't complete," Trump said. "Now we're going to see whether or not Russia's there. And if they're not, it'll be a very disappointing moment for the world."

Responding to Putin's statement, Ukrainian President Volodymyr Zelensky said the Russian leader is setting many preconditions to delay the ceasefire for as long as possible.

In the Oval Office, Trump said the United States had discussed with Ukraine possible concessions as part of a peace agreement.

"We've been discussing with Ukraine land and pieces of land that would be kept and lost, and all of the other elements of a final agreement," Trump said.

Trump's envoy to the Middle East, Steve Witkoff, has arrived in Moscow to meet with Putin and discuss the ceasefire proposal.

"It doesn't mean anything until we hear what the final outcome is, but they have very serious discussions going on right now with President Putin and others, and hopefully they all want to end this nightmare," Trump said, adding that he hopes to speak to Putin soon.
