For some, its not about making a speech or being shot with Mosh. Its a huge global event, for leaders in the financial world. Maxima has shown to have a huge involvement in the field. The conference likely would have been a good source for her, for some of the work she does with her patronages IMO.
Sorry for the confusion, what I meant was that she was not so eager to be photographed with those financial world leaders as Mosh. Max probably had many other opportunities to met those leaders in other occasions due to the Dutch RF's powerful connections and the microcredit program. If she really wants to know the contents of the conference, with the modern technology, she can always watch videos. But if she were invited as a speaker like Rania, she would definitely be there IMO.
