(CNN) – Qatar can be simply defined in the 21st century as the “little state that does.” From near bankruptcy 20 years ago in the face of declining oil reserves and a record budget deficit, the Gulf Arab state with a population of up to 1.6 million, roughly one-fifth of them Qataris, is punching well above its weight.

Qatar’s foray into the global investment arena is hard to miss. Its sovereign fund, the Qatar Investment Authority, has only been around since 2005, but its footprint is a long and wide one. The QIA has taken high profile stakes in German auto giants VW and Porsche, global banks Barclays and Credit Suisse, the London Stock Exchange and British supermarket giant J. Sainsbury and it even bought outright the luxury icon Harrod’s. The big splash year was 2009 when it invested $32 billion on a variety of transactions.

According to Jones LaSalle, the building and real estate group, Qatar was the largest property investor globally in 2010. It has taken high profile positions across London in the Canary Wharf financial district, Chelsea Barracks near the Thames River, and is owner of the current U.S. Embassy in Grosvenor Square.

Prostitution is legal in Germany and income taxable. While collecting tax returns is easier at brothels, getting government revenues from curbside sex workers is more problematic for Germany tax authorities.
