The US says it has evidence Russia has made plans for a “large scale” attack on Ukraine and that Nato allies are “prepared to impose severe costs” on Moscow if it attempts an invasion.

Speaking at a Nato ministers meeting in Latvia, the US secretary of state, Antony Blinken, said it was unclear whether Vladimir Putin had made a decision to invade but added: “He’s putting in place the capacity to do so in short order, should he so decide.

“So despite uncertainty about intention and timing, we must prepare for all contingencies while working to see to it that Russia reverses course.”

He said he had found solidarity among his fellow Nato ministers in the Latvian capital, Riga, saying the alliance was “prepared to impose severe costs for further Russian aggression in Ukraine” and would “reinforce its defences on the eastern flank”.

While repeating the US position that Washington is “unwavering in our support for Ukraine’s sovereignty and territorial integrity, and committed to our security partnership with Ukraine”, the secretary of state stopped well short of saying the US or the alliance would intervene militarily. “Should Russia follow the path of confrontation, when it comes to Ukraine, we’ve made clear that we will respond resolutely, including with a range of high impact economic measures that we have refrained from pursuing in the past,” Blinken said.

He did not specify the nature of those measures, but most observers believe that the Nord Stream 2 pipeline project, intended to bring Russian gas to Europe, could be cancelled if there is another invasion. The new German coalition government is already sceptical about the scheme.

Blinken said the US would spell out the consequences to Russia’s leaders “at the appropriate time”. His remarks represent the strongest warning from the Biden administration so far, and were delivered a day before Blinken is due to meet his Russian counterpart, Sergei Lavrov, in Stockholm under increasingly tense circumstances.

Blinken pointed to “evidence that Russia has made plans for significant aggressive moves against Ukraine”, adding those moves included “efforts to destabilise Ukraine from within, as well as large-scale military operations”.

Ukrainian government estimates of the number of troops near its borders range from 90,000 to 100,000. Russian forces staged two major military exercises in the region, in April and September, and each time left a significant number of troops and substantial supplies of equipment. Commercial satellites have shown concentrations of military vehicles.

Blinken pointed to other possible indicators of Russian intentions.
