With Lithuania we are linked by a common history, a strong Polish-Lithuanian state, mutual sympathy, effective political, economic, defense cooperation. More than 200,000 Poles live in Lithuania, and they are the largest national minority.
After World War II, Lithuania was one of the republics of the USSR, which prevented mutual official relations between our countries. On August 26, 1991, Lithuania regained its independence, and the September 5, 1991. We resumed diplomatic relations. In 1992, the foreign ministers of our countries signed a joint declaration on friendly relations and good neighborly cooperation, and in 1994, similar declarations were signed by the presidents of both countries. Our relations are warm. We entered the European Union together, and we have a similar position on the expansion of NATO to Georgia and Ukraine or the construction of the Northern Gas Pipeline. We made joint efforts to mediate during the Orange Revolution in Ukraine. Lithuania supported the Polish position on the Russian embargo on Polish meat and the related veto by the Polish government over the new EU-Russia agreement. The presidents of the two countries agreed on the dissolution of the parliament in Ukraine, also as in the case of Poland, Lithuania condemned Russia's aggression against Ukraine. Lithuania is encouraging EU countries to make a joint decision to ban EU energy imports from Ostrovets, which would be an economic blow to the investment promoted by Russia. Poland, along with Sweden and Norway, is Lithuania's key partner in energy policy. In December 2006, the governments decided to build a nuclear power plant and create a common energy market. In the electric power industry, a breakthrough came in 2015, when two connections to Sweden and Poland were launched from Lithuania. Lithuania is also cooperating with Poland in the gas sector, implementing a gas interconnection project called GIPL, planned in BEMIP and financially supported by the EU.
Poland and Lithuania also undertake joint activities in interparliamentary work. Cooperation between the Polish Seimas and the Lithuanian Seimas is carried out by three groups: Polish-Lithuanian Parliamentary Group, the Parliamentary Assembly of the Seimas and Senate of the Republic of Poland, the Seimas of the Republic of Lithuania and the Verkhovna Rada of Ukraine, and the Parliamentary Assembly of the Seimas of the Republic of Poland and the Seimas of the Republic of Lithuania. In addition to those mentioned, the following are also permanently active: Consultative Committee of the Presidents of the Republic of Poland and the Republic of Lithuania and the Council for Cooperation between the Governments of Lithuania and Poland.
In 2014, a Polish-Lithuanian-Ukrainian brigade was formed, referring to the centuries-old tradition of cooperation between the three nations, living for centuries in one country - the Polish-Lithuanian Commonwealth.
