John Bolton, United States National Security Advisor met with Polish Defence Minister Mariusz Błaszczak.
“We talked about another location for American troops in Poland, we already agreed upon six, we were discussing the seventh one,” said Mr Błaszczak.
President’s Duda Chief of Staff Krzysztof Szczerski will meet with Mr Bolton later on Friday.
In June Polish President Andrzej Duda and US President Donald Trump signed a joint declaration calling for additional 1,000 US troops to be stationed in Poland. Currently there are about 4,500 American soldiers in Poland, as part of a rotational NATO presence.
Poland has a history of conflict with Russia and the Russian aggression against Ukraine which begun in 2014 only worsened the already strained relations. Deployment of US troops is actively sought by the Polish government as a security guarantee. The deployment is used by the US to balance the Russian influence in eastern Europe.
Mr Bolton is conducting a series of meetings in the region. In recent days he met with presidents of Ukraine, Belarus and Moldova.
He came to Warsaw in conjunction with the planned visit by US President Donald Trump for the commemorations of the 80th anniversary of WWII. Mr Trump cancelled his visit due to a major hurricane approaching the US.
Vice President Mike Pence will come in his place. The wider delegation will include American Secretary of Defence Mark Esper who will take part in talks regarding the possible purchase of the F-35 fighter jets by Poland and Polish industry involvement in the F-35 programme.
President of Ukraine Volodymyr Zelensky will also be present and will meet with both Polish and American officials.
