German Defence Minister Boris Pistorius signed an agreement on Wednesday in Warsaw aimed at strengthening military cooperation with Poland.
Defence Minister Władysław Kosiniak-Kamysz also signed the agreement after paying tribute in parliament to the close partnership with Germany.
The ceremony marked the 35th anniversary of the 1991 German-Polish Neighbourhood Treaty. The neighbouring countries were thus taking responsibility for their future within Europe, Pistorius told journalists.
The NATO eastern flank would be strengthened through closer cooperation.
"There is no security without Poland, without Germany. There is no security without our values, without our membership in the EU and NATO," Kosiniak-Kamysz said.
Pistorius said the agreement opened up new possibilities for cooperation on cybersecurity and cutting-edge technologies, the PAP news agency reported.
The German government said the agreement underscores both countries' commitment to mutual assistance within the framework of the European Union and NATO.
Berlin and Warsaw also aim to work more closely on military capabilities and the defence industry, as well as expanding joint military exercises.
Pistorius announced a deployment exercise dubbed "Grand Eagle" involving 1,200 soldiers from Germany through Poland to Lithuania in November.
The Polish Defence Ministry underlined in particular the areas of military logistics and infrastructure, cooperation in the Baltic Sea region and cybersecurity.
However, the agreement does not contain mutual security guarantees of the kind contained in a Polish-French treaty signed last year.
