Russia said on Tuesday that some units participating in military exercises would begin returning to their bases, adding to glimmers of hope that the Kremlin may not be planning to invade Ukraine imminently, though it gave no details on the pullback.
The announcement came a day after Russia’s foreign minister indicated the country was ready to keep talking about the security grievances that led to the Ukraine crisis — changing the tenor after weeks of rising tensions.
Western officials continued to warn that an invasion could come at any moment and said some forces and military hardware were moving toward the border, muddying the picture.
It wasn’t immediately clear where exactly the troops that the Russian Defense Ministry said were pulling back were deployed or how many were leaving, making it hard to understand the significance. The announcement pushed world markets and the ruble up, but Ukraine’s leaders expressed skepticism.
“Russia constantly makes various statements,” Ukrainian Foreign Minister Dmytro Kuleba said. “That’s why we have the rule: We won’t believe when we hear, we’ll believe when we see. When we see troops pulling out, we’ll believe in de-escalation.”
