LONDON 

The British government on Monday expressed its "unwavering commitment" to collaborate with Sweden to ensure the successful finalization of its NATO membership ahead of the military alliance’s July summit in the Lithuanian capital Vilnius.

The statement came after British Prime Minister Rishi Sunak met with his Swedish counterpart Ulf Kristersson in London.

The leaders discussed the strong friendship between the UK and Sweden, including in defense, security, trade and technology.

Following their meeting, a joint statement was issued emphasizing the importance of Sweden's accession, with the UK asserting that the country's inclusion will not only fortify NATO but also enhance Euro-Atlantic security.

"Sweden is strongly aligned with NATO principles and values, has years of experience training and operating with Allies, including the UK, and will bring a modern and well-trained military into the Alliance," it said.

The two countries also expressed their condemnation of "Russia’s illegal and unprovoked invasion of Ukraine."

"We reiterate our support for Ukraine’s sovereignty and its territorial integrity within its internationally recognized borders. We are leaders in the provision of support to Ukraine: military, humanitarian, economic, and legal."

The two countries also said they viewed China "as a systemic challenge.”

They called on China "not to provide material assistance to Russia or Russian proxies in Russia's illegal war in Ukraine."

In the wake of the Russia-Ukraine war, Sweden is looking to join NATO. However, Türkiye, a NATO member for more than 70 years, has blocked the Nordic country's bid, expressing concerns, especially over the presence of the PKK terrorist organization in Sweden.

Earlier this year, Türkiye ratified Finland's NATO bid, but is holding back Sweden's bid.

NATO leaders will meet in Vilnius on July 11-12 and the alliance’s members are expected to step up support to Ukraine for the long haul and further strengthen deterrence and defense.
