When we launched our [ Vogue] site around five years ago, I had already started this process on paper. We are now building an enormous portfolio of photos, we've uploaded two million photos and we have three people that review them.

I was doing the Black Issue in 2006 and then went to Africa for Uomo Vogue. I've worked with Gucci and Fendi, committed to create jobs. Fifty percent of those ads went to non-government organizations in Africa. [Nelson] Mandela was on the cover, it helped create attention.

There are designers there, we have to think of production, but I am not changing Africa. But if we all do something together....We have to know our limits, I don't have the pretense I can change the world. And I don't want to set up events [to raise money]. Because what happens if the following year they don't have an event, they won't eat?

I say let Matteo Renzi work. He took over a country that was in disarray, not florid. And not the other way around.

Today it's normal. Photos used to be a support to the text, but we turned things around, reducing the words to a minimum.

I think very highly of Expo and all is going well. We've seen big problems with [corruption] scandals [at local government level], but it is going forward, with the highest number of participants ever expected.
