Under the banner of PCD, the OECD and EU emphasize coherence in ODA and non-ODA policies. This study was conceived to improve the policy coherence in Korea and is divided into three sections: analysis of the concept of policy coherence and trade policy coherence, international trends in policy coherence, and policy coherence in Korea and suggestions. To understand the current status in PCD of OECD DAC members, a literature review was conducted and on-site interviews in Sweden, interviews with government officials and advisers and open symposiums were used to compile the opinions of various stakeholders and to make the study findings more relevant.
