Metrovacesa, Spain's largest property company, is looking to expand in Europe as the national market grows increasingly overheated, COO Carlos Vara told Dow Jones Newswires at the Mapic retail property conference in France. Vara said the company is looking to grow through acquisitions in France, Germany, Italy, Belgium and Poland but isn't interested in expanding further east. 'I don't trust Eastern Europe. It is a far more liquid market in the euro zone ,' he added.
