Ukrainian President Volodymyr Zelenskyy has made an unannounced visit to Lithuania, a key ally of Kyiv as it .

Lithuanian President Gitanas Nauseda said in a statement he was welcoming Zelenskyy to his country, where the two leaders would discuss the war and Ukrainian 鈥渋ntegration into the EU and NATO.鈥

Zelenksy said the issue of 鈥渃ooperation on electronic warfare and drones鈥 would also be on the agenda, following on Ukraine in what has been a bloody start to the new year.

Support for Ukraine in the Baltics has remained resolute while it has wavered in Washington. Ukraine in December received its last package of military aid from the United States until a divided Congress approves the Biden administration鈥檚 funding request, which seeks to steel Ukraine as it prepares to enter its third year of war.

Zelenskyy said that what his country is 鈥渟orely lacking鈥 is modern air defence systems. Speaking in Vilnius during a press conference with Nauseda, Zelenskyy said 鈥渞egarding the thing that as of today we are unable to produce short-term together with our partners is modern air defence systems. This is sorely lacking.鈥

鈥淚 think you鈥檝e seen, and journalists know the details, that in the last days of December, the 鈥榟oliday鈥 days for us, and in the first days of January, Russia attacked civilian infrastructure, people, kindergartens, schools, electricity. In total, there were 500 missile and drone strikes. We were able to repel an average of 70 per cent of these attacks. Unfortunately, there were casualties. My condolences to those who lost their loved ones,鈥 Zelenskyy said.

鈥淭hat is why we should fight this enemy with technology until we drive them out of our land and the war is over.鈥

Zelenskyy arrived Wednesday at the airport in Vilnius, Lithuania鈥檚 capital, on a plane bearing the Ukrainian coat of arms. He will then visit the other two Baltic states, Latvia and Estonia, he said on Telegram, without giving a timeline.

The Ukrainian president last visited Lithuania in July 2023 to attend the , where he pushed for a clear path for his country to join the alliance and a timeline for its accession.

But despite Zelenskyy鈥檚 urgency and optimism, US President Joe Biden ahead of the summit that Ukraine could not be admitted to NATO while war was raging on its territory.

Ukraine did, however, secure a streamlined path to future membership. NATO Secretary Jens Stoltenberg said the bloc had changed Ukraine鈥檚 membership path 鈥渇rom a two-step process to a one-step process,鈥 by removing the Membership Action Plan 鈥 a burdensome program of economic, defence and security reforms other recently admitted countries had to go through before joining the bloc.

Zelenskyy received a from the Lithuanian public when he gave a speech in Lukiskes Square during the summit. Addressing thousands on a stage decked out with the blue and yellow of the Ukrainian flag, Zelenskyy said that 鈥淯kraine will make NATO stronger.鈥

Lithuania was the first country to leave the Soviet Union, splitting from the bloc in March 1990. Lukiskes Square once featured a huge state of Lenin 鈥 and large crowds gathered to celebrate its removal in 1991. Many in the country retain deep historical resentment towards Russia, which has fuelled its staunch support for Ukraine.

Arriving in Vilnius Wednesday, Zelenskyy once again expressed his 鈥済ratitude鈥 towards Lithuania. Writing on X, he thanked his ally for its 鈥渦ncompromising support for Ukraine since 2014 and especially now, during Russia鈥檚 full-scale aggression.鈥

According to the Kiel Institute for the World Economy, which monitors and ranks countries鈥 financial support for Ukraine, Lithuania has committed around 1.4 per cent of its GDP in aid for Ukraine 鈥 the second-highest amount among Kyiv鈥檚 allies, behind only Norway.
