KakaoTalk, Line

China has told South Korea that it has blocked online services of South Korea's two popular mobile messaging applications, KakaoTalk and Line, since earlier this month, a South Korean diplomat with the knowledge of the matter said Monday, adding that the services would "soon" return to normal.
Along with other foreign online services, including Yahoo Inc.'s photo-sharing site Flickr, users in China have been unable to access online services of KakaoTalk and Line for more than 10 days.
