The sides are nonetheless far apart, meaning a breakthrough is needed for the conflict to end, the US secretary of state has said

Russia and Ukraine are closer to a peace agreement than at any point in the past three years, US Secretary of State Marco Rubio has said. He cautioned, however, that the sides still need to bridge numerous differences to end the conflict.

In an interview with Fox News on Thursday, Rubio reflected on efforts by US President Donald Trump to settle the Ukraine conflict, a promise he had made while still on the campaign trail.

"For a hundred days he has done efforts to bring about peace... Look, we've gotten closer. We - for the first time - we haven't known this for three years - we kind of can see what it would take for Ukraine to stop. We can see what it would take for the Russians to stop," Rubio said.

However, stark differences between Moscow and Kiev remain, the State Secretary noted. "They're closer, but they're still far apart. And it's going to take a real breakthrough here very soon to make this possible... or I think the president is going to have to make a decision about how much more time we're going to dedicate to this," he added.

His comments come as State Department spokesperson Tammy Bruce affirmed that the US is committed to settling the conflict, but is "not going to fly around the world at the drop of a hat to mediate meetings." Instead, she signaled that it is now up to Russia and Ukraine "to present and develop concrete ideas about how this conflict is going to end."

Last month, the Trump administration indicated that the US could withdraw from the peace process altogether if there is no clear indication of progress in the talks.

Earlier media reports suggested that the US had proposed a peace agreement that includes Washington's recognition of Russian sovereignty over Crimea, as well as "freezing" the conflict along the current front line and acknowledging Moscow's control over large parts of the four former Ukrainian regions which voted to join Russia. The deal would also reportedly prevent Ukraine from joining NATO and initiate a phased removal of the sanctions imposed on Russia.

Russia has maintained that any peace settlement must include recognition of the new territorial reality on the ground, Ukraine's demilitarization and denazification, as well as assurances that Kiev will not join NATO. Ukraine, however, has consistently refused to acknowledge its former territories as part of Russia.
