North Korea will not use Nuclear arms unless threatened.

North Korean leader Kim Jong Un said his country will not use nuclear weapons unless its sovereignty is infringed by others with nuclear arms, and is willing to normalize ties with states that had been hostile
toward it, state media said on Sunday.

Isolated North Korea has made similar statements in the past, although it has also frequently threatened to attack the United States and South Korea, and has defied United Nations resolutions in its pursuit of nuclear weapons.

Kim also set out a five-year plan to boost economic growth, emphasizing the need to improve North Korea's electricity supply, the official Rodong Sinmun said.
