European Union South Korea trade deal comes into force
The European Union's (EU) free trade agreement with South Korea, the most comprehensive it has ever negotiated, comes into force on Friday.
It will remove 98% of listed customs duties, which will cover almost 70% of the trade between South Korea and the EU, says the BBC's Seoul correspondent Lucy Williamson.
Just as important, it includes agreements on intellectual property, services and safety testing.
However, some questions still remain about implementation, with concerns that some agencies are lagging well behind in their preparations for the new trading environment.
