The foreign trades have an important role in developing the percentage of the growth in the production of raw materials sector and use the special economic circumstances in the world to lower the raw materials prices. “L'Expert” went to interview Mr. “Chokri Maameghli” secretary of state in the Ministry of Trade and Art and Crafts. We asked him about the reasons behind the fall of the sector of trade by 18.8% during the first three months of the year (January, February, march) despite the presidential contribution in this sector. According to him the other reasons that contributed to this fall are in relation with the world stock market and the fall of its prices. We asked him too about the lack of balance between the participation of the external (25%) and internal (50%) market in the growth of the first material production. His answer was clear about this point and explained that the unbalance is going to be adjusted soon by progressing the exports and giving more role to the representation in the foreign countries like in middle and east countries of Europe and other African ones. And at the end of the interview we asked Mr. “Maamghli” about how our country is profiting of the economic crisis and he asserted that the crisis is not really affecting the Tunisian economy and the proof is the improvement of the covering's percentage and the decrease of the commercial weakness in some products like the olive oil and the seeds.
