Washington and NATO have been alarmed by the large build-up of Russian troops near Ukraine and in Crimea, the peninsula that Moscow annexed from Ukraine in 2014.
"Russian troops continue to arrive in close proximity to our borders in the northeast, in the east and in the south. In about a week, they are expected to reach a combined force of over 120,000 troops," Kuleba told an online news conference.
"I proposed a step-by-step plan on how to discourage Moscow from further escalation," Kuleba tweeted after addressing EU foreign ministers via video conference. "Key element: preparing a new set of sectoral sanctions. Individual ones are not sufficient anymore."
"In recent weeks Russia has moved thousands of combat-ready troops to Ukraine's borders, the largest massing of Russian troops since the illegal annexation of Crimea in 2014," Stoltenberg said.
"Russia must end this military build-up in and around Ukraine, stop its provocations and deescalate immediately," he said at a news conference with Kuleba. Kuleba said Kyiv wanted a diplomatic solution.
