The Democratic People's Republic of Korea said on Tuesday it had no interest in following Iran down the path of nuclear dialogue, insisting it was already a nuclear weapons state and therefore beyond any logical comparison with Teheran.

One week after the historic deal that cleared a path to lift sanctions crippling Iran's economy in exchange for limits on its nuclear program, Pyongyang rejected any suggestion that it might follow suit.

The DPRK "is not interested at all in the dialogue to discuss the issue of making it freeze or dismantle its nukes unilaterally," its Foreign Ministry spokesman said.
