The public event was held in Dongguan city of the booming Guangdong Province in southern China, considered to be a key area where illegal trade of ivory is reported.
The event, the first public ivory destruction in China, was the country's latest effort to discourage illegal ivory trade, protect wildlife and raise public awareness, state-run Xinhua news agency reported.
Raw tusks and carved ivory pieces, which the government has seized over the years, were dumped into two crushers, the report said on the event held by the State Forestry Administration and the General Administration of Customs.
In the November ceremony, the United States destroyed six tonnes of ivory in a rock crusher.
Conservation groups have been saying that China, which has a vast middle class with growing spending power, is the world's biggest market for ivory.
The international ivory trade was banned in 1989, but black markets still thrive in parts of the world, and poachers kill an estimated 96 elephants in Africa a day to obtain their tusks, according to the Wildlife Conservation Society.
