The United Nations is set to release a detailed report on human rights violations in North Korea, but China has said it will block the report from reaching the International Criminal Court.
The report, to be issued on Monday, is the result of a year-long investigation that includes testimony from former prisoners of torture, rape and murder inside North Korea's labor camps.
The U.N. Commission of Inquiry on Human Rights in North Korea was set up last March to begin building a case for possible criminal prosecution.
However, China - North Korea's closest ally and trade partner - has said it will prevent the report from being presented to the international court. China's Foreign Ministry said that issues concerning human rights should be solved through constructive dialogue.
North Korea denies crimes against humanity are taking place in the country, and labels any criticism of its rights record as a U.S.-led conspiracy.
