In addition to its use in the Olympics, some companies operating in mainland China use the Chinese Taipei flag in place of the ROC flag to represent Taiwan since the PRC does not recognize the ROC.
Court case over IOC decision
The IOC adopted the Nagoya Resolution in November 1979 which called for the "Republic of China Olympic Committee" to change its name to the "Chinese Taipei Olympic Committee" and adopt a new flag and anthem if it wanted to participate in the Olympic Games. The ROC strongly disagreed with the decision and sued the IOC in Switzerland.[2] The ROC claimed that the conditions concerning its name, flag, and anthem violated articles 6, 64, and 66 of the Olympic Charter. However, despite appealing an initial court judgment, the ROC was not successful. On 15 January 1980, a Swiss court rejected the ROC effort to remain in the Olympic movement under the name of "Republic of China."[3][4][5]
Starting at the 2019 Winter Deaflympics a new flag replaced the Olympic rings with the Deaflympics logo. A prior version instead featured a green Chinese dragon and the name "Chinese Taipei" on lower part from the symbol.
