"Then one day sooner rather than later they would like to have a World Cup.
"That is how ambitious they are," added Gosper.
Gosper, who earlier had given the thumbs up to Japan's progress as they prepare to host the first Rugby World Cup to be held in Asia in 2019, said the recent US$100 million investment in the currently low-profile sport - whose Chinese name translates literally as 'English-style olive ball' - by e-commerce giant Alibaba had been the jumpstart rugby required there.
"China has huge potential for anyone in the sporting business literally with the size of market there," said Gosper.
"We are coming from a very low base as we estimate there are about 75,000 players in a population of over a billion.
"However, we have been fortunate enough that a company like Alibaba has through its sports agency Alisports and with help from the sports agency who handles sevens for us agreed an investment strategy with them of $100 million in China over the next 10 years."
Gosper played top level club rugby with the French side Racing, who the likes of Dan Carter and Joe Rokocoko now represent.
The former advertising agent said that aside from the grand designs they had on hosting a World Cup they were going to pour money into every level of the game.
"They want to begin by investing in the professional leagues, sevens and XVs," said Gosper.
"They are also going to invest in grassroots development and school programmes.
"Thus it is a potent mix: the money from the company and the desire of the government to promote team sports as they see it as helping with character building which is something that interests them."
The investment could certainly be a game changer for those who play rugby like China's national rugby captain Ma Chong, who earns 3000 yuan (less than US$500) a month playing for his club.
"As an athlete, I finally see hope for this sport," he told AFP last month.
Gosper, who has been in his present role since 2012, said it was the perfect deal for World Rugby.
"It is very exciting," he said.
"Every department of World Rugby will work with them and put together an investment strategy.
"It's great we can do that with somebody else's money!" he added.
