Nigeria were outplayed at the Shenyang Olympic Sports Centre
A disappointing performance from Nigeria saw them beaten 1-0 by North Korea in their opening game in Group F of the Olympic women's football tournament.
Kim Kyong Hwa scored with a powerful shot inside the penalty area in the 27th minute of a game that North Korea dominated in Shenyang.
North Korea captain Ri Kum Suk put a penalty wide in the 43rd minute, while Ifeanyi Chiejine failed to connect with a cross in second half stoppage-time, an opportunity that could have given Nigeria a point.
With games coming up against Germany and Brazil, who were winners and runners-up respectively at last year's World Cup, Nigeria's chances of getting out of the group seem slim.
Germany and Brazil drew 0-0 in the other game in the group on Wednesday.
