The Canadian company said it has entered into a co-operation agreement with China National Television (CNTV), the new-media broadcast division of China's state broadcaster, CCTV.
DHX will provide more than 700 half hours of children's content initially for the new service.
Some of the series DHX will provide in Mandarin include, "Teletubbies," "Inspector Gadget," "Madeline" and "Sonic the Hedgehog," to be followed by additional DHX titles such as "Caillou," "Super Why!," "Monster Math Squad" and others.
The as-yet-unnamed service will be available nationally in the People's Republic of China (excluding Hong Kong S.A.R., Macau S.A.R. and Taiwan). A launch date has not yet been set.
The deal was announced at a signing ceremony attended by Prime Minister Stephen Harper at the Asia-Pacific Economic Co-operation Summit in Beijing.
"Launching a new children's streaming service with China's official state broadcaster represents a tremendous opportunity to deliver DHX brands to a massive, emerging market," said DHX president Steven DeNure, who was in Beijing for the signing.
