(NYTimes) - Gregory Joinau-Baronnet arrived in Hong Kong about a year ago with little more than a couple of suitcases and a desire to make a living in the wine business. In France, Mr. Joinau-Baronnet had been a real estate agent specialized in selling wine-related property like vineyards. But business ground to a halt as the global financial crisis took hold in 2008. By late 2010, Mr. Joinau-Baronnet had had enough. In January last year, he got on a plane to a place he knew was booming: Hong Kong, which is now attracting immigrants from France faster than its does from the United States, Britain or Germany.
