Reiterates with concern its request to the Secretary-General to ensure that the rules concerning the simultaneous distribution of documents in all six official languages are strictly respected as regards both the distribution of printed copies and the posting of parliamentary documentation on the Official Document System and the United Nations website, in keeping with section III, paragraph 5, of its resolution 55/222 of 23 December 2000; 14. Emphasizes the importance of: (a) Making appropriate use of all the official languages of the United Nations in all the activities of the Department of Public Information of the Secretariat, with the aim of eliminating the disparity between the use of English and the use of the five other official languages; (b) Ensuring the full and equitable treatment of all the official languages of the United Nations in all the activities of the Department of Public Information; and, in this regard, reaffirms its request to the Secretary-General to ensure that the Department has appropriate staffing capacity in all the official languages of the United Nations to undertake all its activities; 15. Requests the Secretary-General to continue his efforts to ensure that, in accordance with their income-generating nature, guided tours at United Nations Headquarters are consistently available, in particular, in all six official languages of the United Nations; 16. Encourages the Secretary-General to continue his efforts to develop and maintain multilingual United Nations websites, from within existing resources, including efforts to keep the Secretary-General’s web page up to date in all the official languages of the United Nations; 17. Reaffirms the need to achieve full parity among the six official languages on United Nations websites; 18. Also reaffirms that the United Nations website is an essential tool for Member States, the media, educational institutions, the general public and non-governmental organizations, and reiterates the continued need for efforts by the Department of Public Information to maintain and improve it; 19.

Requests the Department of Public Information, in cooperation with the Office of Information and Communications Technology of the Secretariat, to continue its efforts to ensure that technological infrastructures and supportive applications fully support Latin, non-Latin and bidirectional scripts in order to enhance the equality of all official languages on the United Nations website; 3
