How Did China Ban Ivory?

China’s ivory market is now closed for business. The country has long been one of the world's biggest consumers of ivory. But as of this year, buying and selling ivory in China is illegal. Carving factories, workshops and jewellers have all shut their doors. How did this happen? And will it be enough to save the African elephant?
