 Mauritania participated in eight Summer Olympic games between its debut in the 1984 Summer Olympics in Los Angeles , United States and the 2012 Summer Olympics in London . Mauritania would participate in the Summer Olympics from 27 July to 12 August 2012 . The Mauritania National Olympic Committee ( NOC ) selected two athletes via wildcards . Usually , an NOC would be able to enter up to 3 qualified athletes in each individual event as long as each athlete met the " A " standard , or 1 athlete per event if they met the " B " standard . However , since Mauritania had no athletes that met either standard , they were allowed to select two athletes , one of each gender , as wildcards . The two athletes that were selected to compete in the London games were Jidou El Moctar , in the Men 's 200 meters and Aicha Fall in the Women 's 800 meters . Moctar was flag bearer for the opening ceremony and a LOCOG Games Maker held it for the closing ceremony .
