[7][8] Before the summit, on 4 July 2023, the former President of Lithuania Dalia Grybauskaitė criticized the Western leaders who failed to prevent the Russian aggression and said that the refusal to invite Ukraine to NATO would be a mistake.

[11] Australia, Japan, New Zealand and South Korea attended the summit to strengthen their ties with NATO due to increasing tensions with China and Russia.

[14] Similarly, German Armed Forces have deployed their MIM-104 Patriot long-range air defense system, placing it in Vilnius International Airport.

[23] In the evening, the Secretary General Jens Stoltenberg hosted a meeting between Turkish President Recep Tayyip Erdoğan and Swedish Prime Minister Ulf Kristersson.

[24] Soon after the announcement, Hungarian Prime Minister, Viktor Orban, stated that Hungary would no longer block the entry of Sweden and would also support their membership into the defence bloc.

However, other nations feared that such quick admittance of Ukraine to NATO could potentially increase Russian aggression and drag out the war even farther.

[30] Stoltenberg has also stated that he expects the summit to create a program of long-term aid over several years for Ukraine: "We have already pledged 500 million euros [US$548m] for critical needs, including fuel, medical supplies, de-mining equipment and pontoon bridges.

"[3] Following the summit, Biden gave a speech at Vilnius University that touched on themes of unity between liberal democracies in the face of Russian aggression.
