South Korea\'s information technology (IT) exports reached a record high of US$156.97 billion in 2011 mainly due to strong overseas demand for smartphones and system semiconductors, a government report showed Thursday. The figure is a 2 percent gain from the $153.94 billion tallied in 2010 and marks the second year in a row that outbound shipments of IT products set new records, the report by the Ministry of Knowledge Economy said.
