But a thread about the incident on Weibo, China's equivalent of Twitter, had been read over 35 million times by Friday, with more than 9,000 comments, most of them unforgiving. Many also continued to post on the rapper's Instagram page.
"The words 'ching chong' were so clear, who would believe you if you said you didn't mean it?" wrote one Weibo user. "The apology is not an honest one, we do not accept and will not forgive."
In the initial post, in a 40-second preview clip of his new single Butterfly Doors, Pump included the lyrics: "Smokin' on dope, they call me Yao Ming 'cause my eyes real low! (Ching chong!)." As he rapped, he pulled the corners of his eyes. The post was later deleted.
The song immediately roused online protest. Chinese rappers, including Sichuan group CD Rev, or Chengdu Revolution, hit back with songs of their own, posting them on Weibo and music streaming websites. Diss tracks, in which artists verbally attack each other, are a key part of hip-hop culture.
CD Rev's song, delivered in English, was titled F*** Lil Pump. Written by the group's Li Yijie, or "Pissy", it attacks Lil Pump's racism, invoking the history of the United States and its treatment of black people and native Americans.
"The fact is you and white racists the same / Respect yourself, you've suffered the pain / You don't know anything 'bout the history / Cuz you a nation of immigrants, and if you really won't take it serious, check it out on those Indians," he raps.
In tweet that has since been removed, American rapper and Crazy Rich Asians actress Awkwafina also criticised Pump for the video's "racist epithet".
