The UN General Assembly adopted last week a resolution -- which passed by consensus without a vote -- condemning the "systematic, widespread and gross" human rights violations in the isolated North.
The impoverished but nuclear-armed nation, ruled by the Kim family through three generations, has been accused of state-sanctioned abuses including torture, rape and extrajudicial killings.
It marked the 14th consecutive year the UN has passed such a document. The North has constantly denied any rights abuses in the country and labelled the UN criticisms as smear campaigns aimed at undermining its leadership.
The North's state-run Rodong newspaper slammed the latest resolution as a "serious political provocation against the (North) and a vicious move to tarnish its international image".
"The wicked intention of the US... in getting vocal about the non-existent 'human rights issue' of the DPRK is to broaden the scope of the sanctions and pressure and escalate them," it said in an editorial, using the North's official name.
The editorial also lashed out at a "thoughtless" South Korea for backing the UN bill -- a move that would be "tarnishing the atmosphere of improving the north-south ties".
Washington had separately sought to organize a Security Council meeting on human rights in the North but gave up on the option earlier this month because it was unsure of the support it would get from partners.
But the US hopes to hold the meeting next month with the arrival of new non-permanent council members that could be more favourable to doing so.
The South's President Moon Jae-in has advocated dialogue with the North to nudge it to denuclearisation negotiations and has met with its leader Kim Jong Un three times this year.
Kim also met with US President Donald Trump in a historic summit in June but progress has stalled with both sides accusing each other of dragging their feet and acting in bad faith.
