Follow-up procedure 49. The Committee requests the State party to provide, by 12 May 2018, information on follow-up to the Committee’s recommendations on the outcome of investigations by the Prosecutor’s Office and the National Police Agency in relation to the death of Mr. Baek, on the outcome of any proceedings in relation to the Sewol Ferry accident, on the closing of remaining “substitute cells” and on the establishment of the office of the military ombudsman (see paras. 14 (d) and (e), 26 and 36 (b)). In that context, the State party is invited to inform the Committee about its plans for implementing, within the coming reporting period, some or all of the remaining recommendations in the concluding observations. Other issues 50. The Committee invites the State party to ratify the core United Nations human rights treaties to which it is not yet party. 51. The State party is requested to disseminate widely the report submitted to the Committee and the present concluding observations, in appropriate languages, through official websites, the media and non-governmental organizations. 52. The State party is invited to submit its next periodic report, which will be the sixth, by 12 May 2021. For that purpose, and in view of the fact that the State party has agreed to report to the Committee under the simplified reporting procedure, the Committee will, in due course, submit to the State party a list of issues prior to reporting. The State party’s replies to that list of issues will constitute its sixth periodic report under article 19 of the Convention. 13
