It will be the first time that Ripeka Te Moananui (17), S'Vania Te Moananui (16), Matthew Bryan-Hunter (17) and Tupou Dean-Harris have ventured into Asia.
They are all New Zealand junior champions.
The invitation to attend the week-long event came from the Shanghai Xu Hui District government, which is keen to promote darts as a school sport.
Twenty-four countries have been invited to send teams to the event which runs from July 31 to August 7.
It will consist of cultural activities, a training camp, a tournament and sight-seeing.
The manager of the team is former Port Chalmers watersider Colin Perriman, who has been playing darts for 45 years, and child youth advocacy worker Mike Te Moananui is the coach.
It will cost the Otago group $12,000 for the trip. The internal costs in China will be paid by the state government.
Fourteen elite professional players have been invited, including Scotty Burnett (United States), one of the best players in the world.
The Otago team management is carrying a letter of intent from Dunedin to invite a team from the Shanghai district to make a reciprocal visit to New Zealand and attend a youth training camp in Dunedin in 2014.
The best player in the Otago team is Ripeka Te Moananui, who has won seven New Zealand junior titles. They include the singles over the last three years, the mixed pairs with Bryan-Hunter and the women's pairs with her sister.
S'Vania Te Moananui was runner-up in the singles this year behind Ripeka. They are both pupils at Queen's High School.
Bryan-Hunter, a pupil at King's High School, teamed with Kaikorai Valley College pupil Dean-Harris to win the junior men's pairs last year at Masterton.
Mike Te Moananui, the father of Ripeka and S'Vania, said darts was a life-long sport and should be encouraged in schools.
"It could lead to a future career," he said. "There is a lot of money to be made by professional darts players."
