In the meantime, the reclusive state is pushing for development of space and nuclear power industries based on self-defensive nuclear deterrence to become a strong and prosperous nation.
This, according to North Korean foreign ministry on Sunday.
The ministry then criticized the five permanent members of the UN Security Council, who recently called on Pyeongyang to refrain from further provocative actions, including a nuclear test, that would threaten regional security.
Accusing the U.S., China, Russia, France and Britain of infringing on its independence, as well as a right to peaceful use of space and nuclear power, North Korea denounced the five nuclear states for conducting and possessing more nuclear weapons than any other country in the world.
