This is a hard question to answer without seeing the work in question. Korean copyright law differentiates between creative content and reporting of facts. Blog posts could be simple reporting of facts (free of opinion) or the could be creative. Reporting of facts is not protected.

The Korean Copyright Commission's site is available in English.

Korea is a signatory to WIPO and to the Berne Convention; thus, Korean law can be applied to British publications.

If it is not a copyright violation, it is certainly bad reporting. A letter of protest to the reporter's editor would be in order.
