Hong Kong is acting as the gateway for illegal ivory entering China - where the item is high in demand.
Prince Charles and Prince William joined launched a campaign to save endangered species like rhinos, tigers and elephants from poachers.
The Duke and Duchess of Cambridge have set up firms to protect their "intellectual property rights," Kensington Palace has revealed.
In a joint video appeal with his son William, Prince Charles said that the illegal wildlife trade now poses "a grave threat" to both endangered species and economic and political stability.

I have said before that we must treat the illegal wildlife trade as a battle, because it is precisely that.
The rising and apparently insatiable demand, much of it from Asia, has provided an economic incentive for trafficking to become increasingly criminalised and professional.
Organised bands of criminals are stealing and slaughtering elephants, rhinoceros and tigers, as well as large numbers of other species, in a way that has never been seen before, pushing many species to the brink of extinction.
Prince Charles and Prince William have released a video appeal to end the illegal wildlife trade, in a bid to save endangered species from extinction.
In the video, Prince Charles describes the illegal wildlife trade as a "battle" and attacks an "apparently insatiable demand" for endangered animals.
The pair recorded the video appeal in six different languages.
The Duke of Cambridge and Prince Harry have reportedly gone hunting in Spain - a day before William and his father, the Prince of Wales, call on the world to combat the illegal wildlife trade.
The royal brothers are set to hunt wild boar and stags on a private estate, according to The Sun.
In a video message due to be broadcast tomorrow, Charles and William will call on people to act now to save endangered animals like rhinos, elephants and tigers.
A royal spokesman told ITV News they would "never" confirm what the princes do in their private time. He added:
"The Duke of Cambridge has for many years been a passionate advocate for endangered wildlife and has campaigned tirelessly to help stop the illegal poaching of rhino horn and elephant tusk. His track record in this area speaks for itself."
Prince William should not be discriminated against because of the circumstances of his birth, a Cambridge University professor has said.
The university has been accused of giving special treatment to the Duke of Cambridge, who got ABC at A-level, but is to start an agricultural course there shortly.
– Prof Ross Anderson, of Cambridge University
Colleagues and I sometimes organise special courses for people from industry who want to learn about the latest research in our field. For this we charge them money.
Every academic has the right to do this, so it is completely unfair of people to criticise poor Borys [Cambridge’s Vice-Chancellor Professor Sir Leszek Borysiewicz].
Whether they have any A-levels at all is no more relevant than the price of tea in China.
Speaking to the Cambridge News, Prof Ross Anderson, of Cambridge University’s Computer Laboratory, defended the rights of his colleagues to produce specialist courses “for people who are prepared to pay for it”.
He added that they should “not be discriminated against on account of the circumstances of their birth”.
Prince William has met with PhD students whom he will be sharing group seminars with on a bespoke course at St John's College, Cambridge University.
The course is part of the executive education programme at the university, and will prepare him for his inheritance of the Duchy of Cornwall estate.
According to a report in the Cambridge News, the modules he is expected to study include farming and supply chains, rural and planning policy, site management, agricultural policy and conservation governance. He will also go on a number of field trips.
The Duke of Cambridge has arrived at St John's College, Cambridge, where he is set to begin a course in agricultural management.
A student newspaper that objected to Prince William's enrolment on a Cambridge University course has withdrawn its criticism.
The Duke of Cambridge is about to start the ten week Agricultural Management course at the School of Technology, to help him prepare for running the Duchy of Cornwall when Prince Charles becomes King.
But student newspaper 'The Tab' questioned whether he had high enough grades to make it onto the course.
Speaking on ITV's Daybreak, the paper's editor Will Heilpern now accepts his enrolment is fair.
"It seemed really unfair that Prince William was coming in to do a degree," he said.
"However, when you actually looks at what he's doing, he's doing a course which is aimed at Boards of Directors and Business Executives so it's not really relevant to compare the grades.
"I was more doing that in a tongue in cheek, jokey manner."
The Duke of Cambridge will return to life as a student today by beginning a course in agricultural management at Cambridge University.
Prince William begins a 10-week course about issues facing the UK's rural communities and the farming industry - preparation for when he inherits the Duchy of Cornwall from his father.
The Duke will have 18 to 20 hours of lectures, seminars and meetings a week and is likely to have essays to complete and to make field trips.
He is expected to live in Cambridge part of the time as he will have accommodation within the city, but will still carry out a number of royal engagements over the coming months.
