The rate of growth of the Tunisian economy in 2013 will be around 4.3%, according to a government estimate which is not optimistic but based on facts, according to Finance Minister Slim Besbes. Besbes told a stock exchange expo in the capital Tunis that next year the economy \'will pick up\' as the government is working on improving conditions in spite of the great difficulties created by the European crisis and the political instability of its neighbour Libya. In order to pursue this objective, Besbes was quoted as saying by the Wbc website, it is necessary that politicians, economists, the private sector and society contribute \'to create a favourable investment climate\'.
