The Committee on Foreign Affairs is responsible for considering and submitting conclusions concerning the ratification and denouncement of international treaties signed by the Republic of Lithuania and other legal acts related to foreign affairs, as well as for carrying out parliamentary scrutiny over matters within the remit of the Committee and exercising other powers established in the Statute of the Seimas.

During the session, regular Committee meetings are held twice a week – on Wednesdays and Fridays. Committee meetings are open when draft legal acts and some parliamentary scrutiny questions are being considered; however, Committee meetings are generally closed. At closed meetings, the Committee considers positions of the Republic of Lithuania regarding legislative proposals of the EU, positions to be taken to the meetings of the Council of the European Union and parliamentary scrutiny over foreign policy.
