United States President Donald Trump says 1,000 more troops will be deployed to Poland.
President Trump said the force would be taken from America’s 52,000-strong contingent in Germany, and include drones and other military hardware.
He fell short, however, of committing to a permanent U.S. base in the country.
It comes after offers from Warsaw to spend $2billion (£1.57bn) on building one.
The base may be called Fort Trump, President Duda quipped during his visit to the White House on Wednesday.
