China has dismissed a UN report accusing North Korea of human rights violations, with analysts believing that the report is a strategy from the US to address nuclear issues in North Korea.

The 372-page report by the UN Human Rights Council, released on Monday, said there are "systemic, widespread and gross human rights violations" in North Korea. The UN investigators said North Korea leaders including Kim Jong-un should be brought before the International Criminal Court for ordering such Nazi-style atrocities.

It's very rare for the UN to declare it will hold the top leader of a sovereign country accountable, Lü Chao, director of the Korean Research Center at the Liaoning Academy of Social Sciences, told the Global Times.

"The report, following year-long interviews with defectors, may largely tell the reality in North Korea, but there are also emotional descriptions involved when defectors, who usually live a miserable life, recall their experiences," Zhang Liangui, a professor at the Party School of the Central Committee of the CPC, told the Global Times. 

North Korea said on Monday that it "categorically and totally rejects the report" and called it an "instrument of a political plot" by hostile forces such as the US, EU and Japan.

The report is one part of the US's multiple measures to address the nuclear issue of North Korea and it is obviously easy to strike down the regime from the perspective of human rights, Zhang said, noting that the report would not prompt Pyongyang to hold back its less confrontational acts.

"China maintains that differences in human rights should be handled through constructive dialogue and cooperation on the basis of equality and mutual respect," foreign ministry spokeswoman Hua Chunying said at a regular press briefing on Monday.

"To bring human rights issues to the International Criminal Court does not help improve a country's human rights conditions," she added.
