"I salute the Polish people for all they are doing to support Ukraine," Boris Johnson said in a tweet late on Thursday.
"The UK stands with you and shares your determination to help Ukraine diplomatically, politically, economically and militarily," he added.
Johnson took to Twitter after a meeting in London with Poland’s President Andrzej Duda during which the two leaders announced "the beginning of a new era in the Poland-UK relationship."
They also said in a statement that their two countries "stand side by side" amid Russia's invasion of Ukraine.
“As Europe faces its biggest security crisis in decades, with a fellow European democracy under attack, Poland and the UK stand side by side,” the statement said.
During the meeting, Duda and Johnson proposed “a Poland–UK Joint Commission to support Ukraine with the long–term co–ordination of arms supplies and training, help Ukraine to identify its needs and modernise its military," according to officials.
Britain, meanwhile, pledged to “triple its support to Poland to £30 million (EUR 36 million) to provide humanitarian assistance to Ukrainian refugees temporarily located in Poland, including temporary shelter, education and other basic services.”
Poland on Friday reported it had welcomed more than 2.57 million refugees fleeing Russia's war against Ukraine.
