The United Nations last week said it would investigate North Korea's rights record. The government is accused of focusing heavily on its military arsenal to the detriment of its people.
The government said last week's decision was a publicity move meant to tarnish North Korea's reputation.
"(It's a) smear campaign against the human rights in North Korea, a desperate effort to evade a shameful defeat in the nuclear standoff with the government and invent a pretext for invasion and pressure," the Yonhap news agency in South Korea quoted Pyongyang as saying.
North Korea drew international rebukes in February when it carried out its third underground nuclear test.
The U.S and South Korean governments signed a deal last week to respond to what U.S. Forces Korea described as North Korean "provocations."
North Korea threatened to use nuclear weapons in response to growing international condemnations. Its February nuclear test was described as part of a campaign against the United States.
