European Union–South Korea Free Trade Agreement per Wikipedia

'... import duties are near eliminated on all produce and there is deep liberalisation in trade in services. It includes provisions for intellectual property (including geographical indications), public procurement, competition, transparency of regulation and sustainable development. There are also specific commitments against non-tariff obstacles on sectors such as automobiles, pharmaceuticals and electronics. '
