US Deputy Defence Secretary Elbridge Colby addressed the issue in a statement on the implementation of the NDS, a document sent to the US Congress.
The statement said the Pentagon was exploring potential opportunities for the permanent deployment of US forces in Poland as part of broader efforts to strengthen military cooperation with key allies.
"We are doing so at the bilateral level through technical talks and other higher-level engagements with key allies focused on military strategy and planning, defence industrial cooperation, and other opportunities to work more closely together, such as ongoing exploration of potential opportunities for permanent basing of US forces in Poland," Colby wrote.
The latest talks took place last week when Polish Deputy Defence Ministers Magdalena Sobkowiak-Czarnecka and Paweł Zalewski met with Colby in Washington.
US President Donald Trump had previously spoken of "major progress" on the issue of a US base in Poland.
One of the two brigade combat teams withdrawn from Europe had been rotationally deployed in Poland, while the other was in Romania.
Colby's statement appears to suggest that the brigade deployed in Poland will not return, Polish state news agency PAP reported.
"We are also undertaking a formal six-month review of US force posture and basing in Europe to ensure that the remaining US presence is appropriately scoped to advance the President’s objectives," Colby wrote in the statement.
European capitals have received questionnaires as part of the review. Colby said the responses had been "substantive."
