Now here is a beautiful story of Trade Creation and Trade Diversion:

Brent Borrell  has the story how Bananarama started; the UN CONFERENCE ON TRADE AND DEVELOPMENT (UNCTAD) has its own report on the Banana Split, an the  BBC supplies the video documenting the happy end. 

That's how I came to grow up in Germany without ever eating a really good banana. That (and the artificially higher cost of European bananas) was the cost of trade diversion. When the EU was formed, a common tariff was imposed to favor consumption of bananas from southern European EU members, rather than Africa and Latin American. The justification was (I am not making this up) " EU officials have conceded that their banana program violates free-trade rules, but have defended it as the by-product of historical and moral obligations to struggling nations dependent on access to the European market."  

This line of reasoning is always a slippery slope – one can easily rewrite the above sentence and replace the term "EU" with the name of any other country in the world, if that argument stuck (and the WTO agreed, many, many times).  Sanctions were imposed (on French handbags, British bed linens !??), to no avail. But then again, the WTO is quite busy investigating all the other free trade infractions (I was stunned to find this website that provides an index of all WTO disputes).
