The value of construction projects in the six Gulf Arab states, plus Iran and Iraq, will reach more than $ 697 billion over the next 10 years, according to figures from MEED magazine. Among these, if only the cost of building stones is 5% of this financial volume, for the next decade, there will be about $ 34.85 billion per year in the consumption field.
Turkey exported $ 33.6 million in 1991, a 20-fold increase to $ 622 million in 2004.
