North Korea's status as a nuclear weapons state can never be reversed, no matter how much the United States and its Asian allies demand it, state media reported on Wednesday, citing the powerful sister of its supreme leader.

North Korea declared Wednesday that its status as a nuclear weapons state is “irreversible,” condemning a joint pledge by the United States, Japan, and South Korea to denuclearize the Korean Peninsula as a “daydream.”

Kim Jong Un's powerful sister slammed US-led efforts to take away North Korea's nuclear weapons, saying the idea of denuclearising the country was a "daydream".
