Ngoc, 17, competed in the women’s 57kg category. The athlete from Can Tho is one of the country’s most outstanding young boxers. She grabbed a silver at the national championships and a gold at the Southeast Asian Youth Boxing Championships earlier this year.
Ngoc was the sole Vietnamese representative at the world tournament in India.
She got a bye to the second round where she beat En Havanur of Turkey 5-0. She then defeated Martinez Roma Linda of the United States 5-0 in the third round.
In the semifinals, Ngoc won 3-2 against Chinese Hu Cailling. Her victory made Ngoc the best Vietnam boxer at a world event.
She, however, lost 1-4 in the final to Chopra Shashi of India and took home a silver medal.
The world tournament, which closed on November 26, attracted 160 athletes from 31 countries and territories, punching in 10 categories ranging from 48 to 81kg.
"We have received confirmation from the International Boxing Association -- AIBA -- about Ngoc. She will take Shashi’s slot at the upcoming Youth Olympics. Shashi will be over 18 next year so she cannot compete," Vu Duc Thinh, general secretary of the Vietnam Boxing Federation, said.
The third Youth Olympics 2018 will be organised in Argentina.
It is the first time Vietnam have a boxing representative at this competition.
