I arrived in Sierra Leone in June 2005, at the height of the rainy season. Mud washed down the pot-holed streets of the capital, Freetown, and knots of beggars, some without arms or legs, huddled under trees and against battered shop-fronts. It was a fortnight before the G8 summit in Gleneagles, Scotland, where Bob Geldof and Bono were to celebrate a huge increase in aid to Africa, but in the Bintumani Hotel no-one spoke of this. Gusts of rain-filled wind blew through the hotel’s porch to set the large red lanterns swinging. Cardboard cut-outs of Chinese children in traditional dress had been stuck on the windows. The management had just celebrated Chinese New Year.It was my first visit to Sierra Leone in more than twenty years’ reporting from Africa, and I was to make a film not about the normal issues covered by British television”orphans, war victims, corruption”but about something few outside Africa seemed to have noticed: the rapidly growing influence of China in the continent.
