Recently, the FTA between China and Korea is under investigation. The purpose of this thesis is to suggest the criteria for determining the country of origin when the FTA between China and Korea is negotiated. It is very important to know the Rules of Origin(RoO) when two countries sign free trade agreements because it can affect their economic interests directly. This study firstly analyzed and compared the legal system and basic principle on the RoOs already signed between China and Korea, and then suggested criteria for origin determination for individual products of China and Korea by the industrial difference between China's and Korea's tariff rates, the industrial difference between China's and Korea's trade balance of payment, and the industrial difference between China's and Korea's import market share.The result of this study will expect to provide a practical reference for any policy consideration in the RoO negotiation when the FTA between China and Korea is negotiated the FTA. Key Words: FTA, Criteria for origin determination, Rules of Origin(RoO)
