HONG KONG (AFP) - Hong Kong's government is considering destroying its stockpile of over 30 tonnes of ivory obtained through seizures of elephant tusks, it said on Wednesday.

The Chinese government crushed a pile of ivory weighing more than six tonnes on Monday, its first public destruction of ivory, to discourage illegal trade.

"The Agriculture, Fisheries and Conservation Department is aware of the steps taken in other places to destroy forfeited ivory," the Hong Kong government department said in a statement sent to AFP on Wednesday.

The department said it is "reviewing the effectiveness of the existing disposal measures" and drafting a proposal for the destruction of forfeited ivory.

Hong Kong has been a transit point for the ivory elephant tusk trade. The southern Chinese city has seen tusk seizures rise steadily since 2009, reaching a record amount of 8,041kg seized in 2013.

Having seized 33.37 tonnes of tusks since 2003, mostly shipped from African nations by sea, some of the stockpile has been used for educating school children on the harmfulness of the trade. But conservation groups have lobbied for the stockpile to be completely destroyed.

"I think they're going to do it because China has done it, the US has done it, it's a trend now, that's the way it seems to be moving forward," Hong Kong for Elephants campaigner Alex Hofford told AFP.

"It will send a very strong signal to consumers in China that buying ivory is wrong," Mr Hofford said, adding that tourists from the mainland in Hong Kong are the ones supporting up the ivory trade in the city.

Surging demand for ivory in Asia is behind an ever-mounting death toll of African elephants, conservationists have said.

Experts believe that most illegal ivory is headed to China - where products made from the material have long been seen as status symbols.

Another endangered animals activist Sharon Kwok said that destroying the stockpile will signify to consumers from the mainland that buying ivory is no longer viable.

"They would be running scared and looking for something else to do," Ms Kwok told AFP.

The US crushed six tonnes of ivory in November while the Philippines destroyed five tonnes of tusks in June, and Kenya set fire to a pile weighing the same amount in 2011.

Ivory trading was banned in 1989 under Cities (Convention on International Trade in Endangered Species of Wild Fauna and Flora), an international agreement between governments, but as poaching has continued environmental group WWF estimates there could be as few as 470,000 African elephants left.
