Trump made the remarks in an interview on Fox News Channel's Sunday Morning Futures with Maria Bartiromo.
Being able to find a buyer could allow TikTok to continue operating in the  United States amid national security concerns over a Chinese firm's ownership of the platform.
"We have a buyer for TikTok, by the way," Trump said.
"I think I'll need probably China's approval. I think President Xi (Jinping) will probably do it."
Under former US president Joe Biden's administration, Congress had passed legislation requiring TikTok to cut ties with its Chinese parent company ByteDance and secure ownership by an investor from a country not deemed a "national adversary" by January 20, the day Trump took office again.
When no deal was reached by the deadline, TikTok briefly went offline in the US until Trump, on his first day back in the White House, signed an executive order granting a 75-day extension.
On April 4, he provided an additional 75-day extension, and on June 19 extended that again by 90 days, pushing the deadline to September 17.
Trump, who has expressed fondness for the app, reiterated that TikTok played a role in his election victory by boosting his popularity among younger voters.
"I have a soft spot for TikTok," he said.
