North Korea has condemned a new security pact between the US, UK and Australia, saying it could trigger a "nuclear arms race".
A Foreign Ministry official said the Aukus deal would "upset the strategic balance in the Asia-Pacific region".
The deal will see the US and UK give Australia the technology to build nuclear-powered submarines.
It is being widely viewed as an effort to counter China's influence in the contested South China Sea.
The Aukus pact was announced last week and will also cover cruise missiles, Artificial Intelligence and other technologies.
"These are extremely undesirable and dangerous acts which will upset the strategic balance in the Asia-Pacific region and trigger off a chain of nuclear arms race," said a DPRK Foreign Ministry official referring to the security agreement.
Last week, North Korea carried out two major weapons tests - that of a long-range cruise missile and a ballistic missile.
China has also criticised the deal with Beijing's foreign ministry spokesman Zhao Lijian saying the alliance risked "severely damaging regional peace... and intensifying the arms race".
Pyongyang said it was "quite natural that neighbouring countries [like] China condemned these actions as irresponsible ones of destroying the peace and stability of the region".
The deal will see the US share its submarine technology for the first time in 60 years, having previously only shared it once with the UK.
