The president of Poland has told President Donald Trump that he would like the US to create a permanent American base in Poland that would be named Fort Trump.
Trump said he was considering the idea and that Poland has offered more than $US2 billion ($A2.8 billion) to the US to pay for such an effort.
The comments came at a joint White House press conference by the leaders on Tuesday.
Trump said they had agreed to bolster defence, energy and commercial ties. He said the alliance between the two countries has "never been stronger".
Poland has been pressing for the 3000 US troops now deployed in Poland on a rotating basis to be upgraded to a larger, permanent presence as it faces Russia's increased military activity in the region.
