Brussels, 05/08/2005 (Agence Europe) - On 1August, the Organisation for Security and Cooperation in Europe (OSCE), which is composed of 55 participant States and extends from Vancouver to Vladivostok, celebrated the thirtieth anniversary of the Helsinki Agreements signed notably by Gerald Ford, Leonid Brejnev and Helmut Schmidt in the Finnish capital on 1 August 1975. The agreements signed by 35 countries founded the Conference for Security and Cooperation in Europe (CSCE), which became the OSCE in 1995. The final Helsinki Treaty was the real charter for détente, it was a charter not only for relations between States but also for the freedom of nations and individuals, the President of Finland, Tarja Halonen, stressed on Monday during a ceremony also attended by Slovenian Foreign Minister Dimitrij Rupel in his capacity as president-in-office of the organisation currently attempting reform. Recalling that an experts' report recommends a package of measures to make the OSCE more effective, Dimitrij Rupel called on the leaders of the participant States to show proof of “the same political courage” as that which prevailed thirty years ago.
