Ireland\'s trade surplus narrowed in June from May as exports grew slower than imports, official data showed on Wednesday. A trade surplus is one of the main factors of growth in an economy and eurozone nation Ireland, which is fighting to break out of a bailout programme, is counting heavily on exports to help it emerge from its debt crisis. The trade surplus fell to 2.989 billion euros ($3.963 billion) in June from 3.064 billion euros in May, the Central Statistics Office said in a statement.
