US-South Korea nuclear deal raises concerns in Russia.

Russia's foreign ministry has criticised the nuclear agreement between the United States and South Korea, warning of potential destabilisation in the region and a global arms race. The US pledged to give South Korea more insight into its nuclear planning, while Seoul promised not to seek nuclear weapons itself in an agreement aimed against North Korea. Russia has repeatedly opposed the US' growing military presence across Asia and accused it of seeking "decisive military superiority" that could provoke an arms race.
