The Women's Asian Cup has faced a notable controversy after a former coach of Taiwan's men's national team, Chen Kuei-jen, was ejected from a match for leading a pro-Taiwan chant. This incident occurred during a group stage match against India at Parramatta Stadium, where Taiwanese officials expressed their discontent with the ejection, citing it as a political suppression that further complicates the already delicate relationship involving Taiwan's international representation and identity in sports.

The chant, which included the phrase 'Taiwan: add oil!' was interpreted as a rallying cry for Taiwanese supporters, however, it was deemed inappropriate by match security who argued it constituted a political slogan. The incident took place just before the highly anticipated quarter-final between China and Taiwan, exacerbating sensitivities around the use of the name 'Taiwan' due to the complex geopolitical issues between the two entities, particularly within competitive sports governed by organizations like the Asian Football Confederation.

This incident highlights not only the ongoing political tensions surrounding Taiwan's identity in international forums but also the potential consequences sports can have in diplomatic relationships. As Taiwan continues to navigate its unique position on the world stage, this case raises questions about the right to express national identity in public and sporting events, and the broader implications for athletes and supporters both locally and internationally.
