Taiwanese taekwondo athlete Yang Shu-chun was disqualified with twelve seconds remaining in the first round due to "unauthorized" (disputed) sensors on her socks.
Yang was facing Vietnamese opponent Vu Thi Hau in the first round of the flyweight division (under 49 kilogram) of the Asian Games taekwondo competition in Guangzhou, Guangdong, China on November 17, 2010, when she was accused of using the "unauthorized" sensors.
[3] Chinese Taipei representatives at the taekwondo venue immediately pointed out that the equipment was certified and that both fighters passed a pre-match inspection.
[6] The equipment supplier of the Chinese Taipei team said they had never received an official notification from the WTF about suspending the velcro type socks before the Asian Games.
The Democratic Progressive Party (DPP) legislator Pan Men-an (潘孟安) claimed at a press conference that the accusation by the Game officials that Yang had cheated was an "insult to everybody around the country," and charged that, "the responsibility should fall on the people that conducted the equipment checks.
The DPP Legislator Chiu Yi-ying (邱議瑩) complained that: "A large number of officials attended the Games, but all they have done so far is to show up at and take part in the awarding ceremonies when our athletes win.
Tsai Ing-wen (蔡英文), then-current chairperson of the DPP and a candidate for mayor of New Taipei City in 2010, released a statement saying: "This government has always deferred to China and hasn't emphasized our attitudes enough, especially on sovereignty issues."
[13] The Asian Taekwondo Union published a misleading article titled "Shocking Act of Deception by Chinese Taipei" on its website, attempting to deflect South Korea of blame of the incident.
[14] Since this is not the first time that Taiwanese athletes have faced controversial judgments in international games, netizens rallied to boycott Korean merchandise.
Her coach, Liu Tsung-ta was given a 20 months' suspension while Chinese Taipei Taekwondo Association (CTTA) was fined US$50,000 for "negligence and wrongdoing".
