BERLIN, May 19 (Reuters) - Germany’s DIHK Chambers of Industry and Commerce said on Wednesday it slightly raised its growth forecast for Europe’s largest economy to 3% this year after its recent survey pointed to improved business morale over the past three months. The DIHK’s updated growth forecast compares with its previous estimate of 2.8% projected in February and is based on the latest findings of the association’s survey among more than 27,000 companies from various sectors of the economy. The DIHK forecast is less optimistic than the government’s projection of 3.5% GDP growth this year.
