Not sure I see the logic there. Ireland hasn't been blessed with the natural resources or heavy industry that Britain has, so traditionally there was no option but to import oil, coal, steel, etc.
The shift in the import/export balance has a lot to with Ireland shifting to a service-based economy, which is thanks to more recent developments areas such as tech and banking. In terms of tangible exports, that's thanks to the growth of Irish food companies to become major players on the world market.
