The South Korean government has persuaded the World Trade Organisation (WTO) to investigate an anti-dumping complaint against the US.
The state claims that the US has imposed unreasonable anti-dumping duties on South Korean products and the US has now been forced to accept WTO arbitration.
The WTO has established a dispute panel to arbitrate between the two countries, following a complaint South Korea made last August that it had not been guilty of dumping memory chips. In that case, it argued, it was unreasonable for the US government to maintain its regulations and penalties.
The complaint also centres around a decision made by the US Department of Commerce that the burden of proof for ending anti-dumping penalties should be on Korea.
Attempts by both parties to solve the dispute had come to nothing, according to the South Korean government.
While the US government attempted to block the panel of three neutral arbiters being set up, US ambassador Rita Hayes was forced to accept the arbitration last Friday.
