Many Chinese celebrities have issued public statements cancelling further cooperation with Italian fashion brand Dolce & Gabbana after it posted a controversial video on Sunday that many deemed racist against Chinese people.

The brand's ambassador in China, singer-actor Wang Junkai, announced via his studio that he and his office have broken off any previous engagement with the luxury brand.

"The premise of cooperation lies on exchange on equal grounds and mutual respect, as well as respect for each other's culture and history. One's motherland is not to be infringed upon, and one's motherland stands above all.

We here announce to rescind the contract with Dolce & Gabbana.

Starting tomorrow, Wang Junkai and Wang Junkai Studio will terminate all cooperation with Dolce & Gabbana," according to a statement released on the official Sina Weibo account of the star's studio last night.

Actress Dilraba Dilmurat, who has served as the brand's ambassador in the Asia-Pacific region, also issued an official statement rescinding all engagement with Dolce & Gabbana after the incident.

Wang personally showed support for his nation through social media as well.

"Beyond all doubt, you are the best CN (China)," the actor wrote on his Weibo account.

Dilraba echoed Wang's attitude with a post on her Weibo account, which read "Love you, our beloved motherland?CN."
