Norwegian Prime Minister Erna Solberg opposes some of NATO's proposed reforms, including steps to mitigate climate change, fearing that the Western alliance could take on too many additional responsibilities, Reuters reported.

At the June 14 summit, NATO members, including Norway, will discuss Secretary-General Jens Stoltenberg's plan to revitalize the alliance, known as NATO 2030, aimed at confronting Russia and China, countering terrorism, cyber-attacks, technology, and climate change.

Solberg said Stoltenberg risks taking on too many responsibilities.
