(BusinessTimes) - A Chinese industrialist has completed the landmark purchase of Chateau Bellefont-Belcier, a leading estate in France's prestigious Saint Emilion wine-making area, sources involved in the sale said on Thursday. The property is the first of its rank - Grand Cru Classe (classified growth) - to be acquired in what has been a wave of Chinese investment in the Bordeaux region. The new owner is a 45-year-old industrialist with assets in the iron sector who has already diversified into the wine importing business. He met the chateau's employees on Friday and has since returned to China.
