The decision came after China had imposed a three-year ban on ivory imports in March this year, in an escalated fight against illegal trading of wild animals and plants.
"China will gradually stop the processing and sales of ivories for commercial purposes by the end of 2017," state-run Xinhua news agency quoted an official statement.
The move will impact China's 34 processing enterprises and 143 designated trading venues, with dozens to be closed by the end of March 2017, the statement said.
China's move, if implemented, strictly could a "game changer", specially the African elephant conservation as hundreds killed every year by poachers to feed into the burgeoning markets in China and Hong Kong.
