In an article titled “We need European unity,” Morawiecki analysed the tension around Ukraine, amid a threat of Russian invasion.
“For many generations of young Europeans, the outbreak of war was never so close,” he wrote, adding that “for many years, the West wanted to believe that the 21st century will be free from conflicts.”
The Prime Minister also stressed that Russia is “once again trying to violate Ukraine’s territorial integrity,” which he called “an assault on European peace.”
Washington warned on Friday that Russia was massing yet more troops near Ukraine and that an invasion could come at any time, perhaps before the end of this month's Winter Olympics, according to Reuters.
US Secretary of State Antony Blinken told the media that there "very troubling signs of Russian escalation, including new forces arriving at the Ukrainian border."
He said: "We're in a window when an invasion could begin at any time, and to be clear, that includes during the Olympics."
The Beijing 2022 Winter Olympic Games end on February 20.
Russia annexed the Crimea peninsula from Ukraine in 2014 and then fomented a separatist conflict in that country's eastern Donbas region, leading to a wave of EU and US sanctions against Moscow and Russian officials.
