Not to be perverse, but I am happy to announce that there is a strong relationship between the OSCE and the United Nations. This is not surprising when we consider that the UN was formed October 24 st 1945. This was at the conclusion of the 2nd WW. I have no problems with the UN. I never have. I think they work with what they have and are often opposed. Nonetheless, the Charter is genuine and I for one believe in it.
My interest in the WTs attendance at the OSCE, was to show that the society found a way around the embarrassing publicity of their membership with the UN. And here we have them attending a very closely aligned organization that (of course) reports back to the UN. It would be counter productive NOT to. For, information sharing in terms of what is going on with other countries, is imperative to remaining close to what may or may not be a threat...

One of OSCE's closest partners is the United Nations. Co-operation was inititated in 1992, when the participating States declared the OSCE to be "a regional arrangement in the sense of Chapter VIII of the Charter of the United Nations".
The wide-ranging text reaffirms the primacy of the United Nations Charter for maintaining international peace and security, but expresses the Council’s intention to expand cooperation, as appropriate, with relevant organizations.http://www.un.org/press/en/2013/sc11087.doc.htm
