Secretary of State Antony J. Blinken said on Wednesday that Russia’s intentions behind its latest military buildup along Ukraine’s eastern border were unclear, but that Moscow would be making a “serious mistake” by committing new aggression against its embattled neighbor.
“We don’t have clarity into Moscow’s intentions, but we do know its playbook,” Mr. Blinken said at a joint news conference at the State Department with Ukraine’s foreign minister, Dmytro Kuleba.
“Any escalatory or aggressive actions would be of great concern to the United States,” Mr. Blinken added.
