1 Any competitor in the Olympic Games must be a national of the country of the
NOC which is entering such competitor.
2 All matters relating to the determination of the country which a competitor may
represent in the Olympic Games shall be resolved by the IOC Executive Board.
这个看怎么理解national吧,如果概念那么清晰的话,就不会有issues resulting from nationality, citizenship, domicile or residence of any competitor。
或许谷代表中国baseed on her Chinese Nationality, not American Citizenship,谁知道呢。
