"The Estonian, Latvian, and Lithuanian defence ministers met to that end in Brussels today and signed a joint communiqué to facilitate movement of allied forces in the region and simplify related bureaucratic procedures concerning NATO enhanced Forward Presence troops deploying into the Baltic states and Poland," it said in a press release.

Poland is expected to sign a similar agreement on Thursday.

Brussels on Wednesday is hosting a meeting of NATO defence ministers.

In response to Russia' intervention in Ukraine, the Alliance decided last year to station around 1,000 troops in Lithuania, Latvia, Estonia and Poland each.
