Foreign policy
At the beginning of her first term, Grybauskaitė tried to reset relations with Russia and check whether pragmatic relations with Russia were possible. In 2010, Grybauskaitė even met with Russian Prime Minister Vladimir Putin in Helsinki. After her presidency, Grybauskaitė described the meeting as a clarifying point, stating "I realised that this person and country is not willing to accept their neighbors honorably, that they are trying to make you kneel on your knees; Either you give in, or you are the enemy." During the meeting, according to her, Putin presented a list of demands to fulfill, encompassing increasing the interconnectedness and interdependence of the Lithuanian–Russian energy sectors. The president found these unconsiderable as an avenue for the Russian coercion. After this meeting, relations between Lithuania and Russia began to cool down.
On 19 December 2013, Grybauskaitė decided to boycott the Sochi Winter Olympics together with other Western leaders, including German president Joachim Gauck, French president François Hollande, and the US president Barack Obama, due to Russia's human rights violations, attitudes and behaviour with Eastern partners and Lithuania. Relations with Russia markedly deteriorated during Grybauskaitė's second term in office, due in part to her hard line stance against Russian influence in Europe and the Baltics, especially after the start of the Russo-Ukrainian War. In May 2014, Grybauskaitė called the dependence on Russian gas an "existential threat" to Lithuania.
Following her reelection in May 2014, Grybauskaitė said "Dignity, self-respect and mutual benefit, these are the principles that should set the basis for relations between countries and no doubt, knowing that this is our neighbor, we wish this country to democratize and cope with the arising economic challenges". In June 2014, Grybauskaitė told the German news magazine Focus: "[Putin] uses nationality as a pretext to conquer territory with military means. That's exactly what Stalin and Hitler did." She also claimed that Russia and Putin were "characterised by aggressiveness, violence, and a willingness to overstep boundaries."
On 20 November 2014, Grybauskaitė, commenting on the Russo-Ukrainian war, characterized Russia as "a terrorist state which carries out an open aggression against its neighbors". In June 2018, Grybauskaitė said that Lithuania should be ready for Russian invasion. She also said that Western states will "wake up" only "when they have been attacked" by Russia. In December 2018, Grybauskaitė told Ukrainian President Petro Poroshenko that Lithuania would increase military assistance to Ukraine: "We will additionally supply more ammunition, send more military instructors and cyber security experts to help repel hybrid attacks, especially during the elections."
In December 2014, Grybauskaitė said that Lithuania will have to take the responsibility for the secret CIA-operated prison in Lithuania. Regarding British Prime Minister Theresa May's comments on acting as a "bridge" between the European Union and the United States, Grybauskaitė said that "I don't think there is a necessity for a bridge. We communicate with the Americans on Twitter." In March 2017, Grybauskaitė criticized the government of Poland and Prime Minister Beata Szydło for not endorsing Donald Tusk again for the President of the European Council.
In January 2019, Grybauskaitė said a "no-deal Brexit" would be better than delaying Brexit. She said the EU would negotiate mini or sectoral arrangements to mitigate a no-deal scenario.
