A Chinese talk show host has accused a Canadian government-backed tourism organization of censoring discussion of the country's Aboriginal issues on his program and says it caused an episode to be dropped.

Gao Xiaosong, also head of Alibaba Group Holding Ltd's music division, made the accusation on his Weibo Chinese microblog on Saturday, two days before Canadian Prime Minister Justin Trudeau embarked on his first official visit to China.

Gao wrote that he had interviewed a Canadian aboriginal chief for an episode of his show, "Xiaosong Pedia," due to be shown last Friday on the online video site iQIYI.
