Fiji has its first-ever Olympic medal – and it's gold to boot. Now that's a reason to party.

The Pacific Island nation erupted with joy Friday after its rugby sevens team crushed Britain 43-7 in final in Rio de Janeiro.

In the capital of Suva, fans packed the 15,000-seat National Stadium to watch the Olympic final on a big screen – held Thursday night in Rio but at 10 a.m. Friday back home. Tense at first as they saw their nation on the brink of an historic achievement, fans relaxed and then rejoiced as Fiji ran away with the victory.

Prime Minister Frank Bainimarama, in Rio for the games, told reporters ''rugby has always lifted the spirit and always brought us together. Right now, whatever political party, there's no difference. Everyone is coming together to celebrate.''

He declared a public holiday for Aug. 22, the day after the team returns home.

Chinese officials say a female Chinese swimmer has tested positive for a banned substance at the Rio Olympics – the first competitor in the sport to fail a test at the games.

The Chinese Swimming Association says 18-year-old Chen Xinyi has tested positive for the diuretic hydrochlorothiazide after she finished fourth in the women's 100-meter butterfly Sunday, missing a bronze medal by nine-hundredths of a second. Xinhua, China's official state news agency, reported the story Friday.

Chen was also scheduled to compete Friday in the 50 meter freestyle.

Chen has applied to the International Olympic Committee to have her B sample tested and to get a hearing on the matter, Xinhua said, citing the swimming association, which promised in a statement to ''take this matter seriously.''
