These markets are dependent on the price of oil. Taking into account the Qatar market the challenges faced would be

-Alternative Fuels
-A Reality Check… DSM20 (Doha Securities Market) melting down from 12000 to 6000 in 2005-06
-Stability in the region
-S&P rating moving down from positive to stable
-High Public debt

The reason for investing - (i.e Qatar)

-GDP: US $ 30 billion growing at 9% pa
-Mkt Cap: US 54 $ billion of around 36 listed companies
-Current Hydrocarbon production: 6 billion cu… targeted 25 billion cu
-Planned Investment in Infrastructure: US $ 130 billion
-Per Capita Income: US $ 35,000
-Prestigious Projects:
-Qatar Bahrain Causeway - US $ 3 billion
-Doha Airport to handle 12.5 million passengers by 2009 and 50 million by 2015

My yield from the Indian market is and will surpass any Investment in the middle east.

Period.
