To ensure a more efficient cooperation between the countries and to facilitate the implementation of bilateral projects, in 1997, three joint institutions – the Advisory Committee of the presidents of Lithuania and Poland, the Lithuanian-Polish Interparliamentary Assembly, and the Lithuanian-Polish Council of Intergovernmental cooperation – were founded. Bilateral cooperation became very close and intensive with the election of Valdas Adamkus and Aleksander Kwaśniewski presidents of the two countries. Poland was an important ally to Lithuania in the country's bid to attain EU and NATO membership, both presidents acted as mediators during the Orange Revolution in Ukraine, and the countries still agree on foreign political threats and the importance of energy independence. Later, there has been some tension in the relations due to the controversy over the situation with ethnic minorities and the disputes over the spelling of Polish personal and place names and Polish schools in Lithuania.

With the changes that occurred in the geopolitical situation of the region in 2016 and energy and transportation infrastructural projects underway, the relationship between Lithuania and Poland is recovering, Poland is actively involved in ensuring the security of the Batic region, its troops are continuously participating in NATO military training exercises in Lithuania.
