We must bring a message of solidarity, of mutual respect and, above all, of hope. Business cannot afford to be seen as the problem.

It is not in the United Nations that the Millennium Development Goals will be achieved. They have to be achieved in each of its Member States, by the joint efforts of their governments and people.

We need to think of the future and the planet we are going to leave to our children and their children.

The Arab spring reminds me a bit of the decolonisation process where one country gets independence and everybody else wants it. How about us, when do we get it, when do we make our move? And you have a situation where someone has been in power for decades, where the integrity of elections, democracy and security have really not been debated or discussed and most people suspect that elections are rigged and that the democratic rotation that elections are supposed to ensure doesn't really happen. And when this goes on for a while you are sitting on a powder keg.

Some have suggested that ideally there must be some international body that would treat areas like the Arctic as a global commerce, a bit like the way we treat the sea. It doesn't belong to any particular country, but to all of us, but I'm not sure some of the powerful are ready for that sort of solution.

I can't think of a 30- or 40-year-old who can behave like Mugabe. They wouldn't even know where to begin, and given their own educational exposure, I think it will be very positive for Africa.

There has to be a force on the horizon that can come very quickly. But the way we run and fund peacekeeping, this capacity is unavailable.
