United Nations human rights body agreed today to enhance its investigation into the violations in North Korea with a view to documenting alleged crimes against humanity for future prosecution. <br/><br/>The 47-member State Geneva forum adopted a resolution, brought by Japan and the European Union and supported by the United States, on the final day of its four-week session without a vote. <br/><br/>North Korea's delegation boycotted the debate. The U.N. human rights office in Seoul will be strengthened for two years to establish a central repository for testimony and evidence with a view to developing possible strategies to be used in any future accountability process, the resolution text said. China opined it dissociated itself from the decision and called for dialogue and an emphasis on the bigger picture to help de-escalate tensions on the Korean peninsula.
