The state Department of Employment and Economic Development is reporting a record fourth quarter for Minnesota exports.  Companies exported four-point-six-billion dollars in manufactured products over the last three months of 2010.  DEED Commissioner Mark Phillips says exports climbed at a consistent pace all year - increasing by more than 17 percent from 2009.  Canada continues to be Minnesota's largest trade partner with one-point-three-billion dollars worth of fourth-quarter exports.  China, Japan, Mexico and Germany round out the top ten.  Computers and electronics were the state's top exports.
