President Nazarbayev has turned Kazakhstan into a Central Asian powerhouse. He is 73, and shows no sign of giving up the reins. But there are riches at stake, and people waiting in the wings. Kazakhstan has won kudos from international investors, for having successfully exploited its oil and gas reserves, ensuring GDP growth of 5% a year and annual GDP of over £120 billion, with a population of less than 17 million; and a landmass covering an area greater than continental Europe. The country is bidding to join the world's top 20 economies by 2050. The building of a modern capital city, Astana, in 1997, at very considerable expense, is another facet to this modernisation.
