FILE - In this May 19, 2014 file photo, Japanese figure skating star Mao Asada arrives for a press conference in Tokyo held two months ahead of an figure skating event sponsored by Lotte. When South Korean Chung Yu-suk read an article about retailer Lotte's chocolate ads featuring Asada, he was so angered he started an online group urging Koreans to boycott their country's top retailer. Chung is one of a growing number of South Koreans vowing to punish Lotte after a family battle for control of the company spilled out in public and highlighted their deep links to Japan, Korea's former colonizer.
