Sand from Germany on its way to Dubai – selling coal to Newcastle

Dubai is a land with plenty of sand in its deserts but, it is importing sand from Germany – it is similar to selling coal to Newcastle or selling a refrigerator to an Eskimo.
A German firm has agreed to supply Dubai with 1500-square-meters of sand which is to be used on the oil rich city's famous racecourse.
That is why, in spite of having an abundance of sand with it, Dubai has to go in for importing it.
The specially sifted sand from Germany is necessary because the local sand is allegedly too unstable for horses to race on, hence the decision to transport the right type of sand all the way from central Europe.
As reported by the officials at Dubai's race tracks and training yards, the local sand is 'too coarse' for their multi-million pound thoroughbreds.
Incidentally, The Dubai World Cup, which is held at Meydan racecourse every year has a cash prize of $10 million, the biggest in horse racing – it is being held annually since 1996.
