ByteDance has an April 5 deadline to find a non-Chinese buyer for TikTok or face a US ban on national security grounds that was supposed to have taken effect in January under a 2024 law.
The law is the result of concern in Washington that TikTok's ownership by ByteDance makes it beholden to the Chinese government and that Beijing could use the app to conduct influence operations against the USand collect data on Americans.
Trump said he was willing to extend the April deadline if an agreement over the social media app was not reached.
He acknowledged the role China would play to get any deal done, including giving its approval, saying "maybe I'll give them a little reduction in tariffs or something to get it done".
TikTok did not immediately comment.
During a regular news conference on Thursday, China's commerce ministry said its position on the tariff issue was consistent and that Beijing was willing to engage with Washington on the basis of mutual respect, equality and mutual benefit.
Trump's comment suggests the sale of TikTok is a priority for his administration and is important enough to use tariffs as a bargaining chip with Beijing.
In February and earlier in March, Trump added levies totalling 20 per cent to existing tariffs on all imports from China.
Getting China to agree to any deal to give up control of a business worth tens of billions of dollars has always been the biggest sticking point to getting any agreement finalised.
Trump has used tariffs as a bargaining chip in the TikTok negotiations in the past.
On January 20, his first day in office, he warned he could impose tariffs on China if Beijing failed to approve a US deal with TikTok.
Vice President JD Vance has said he expects the general terms of an agreement that resolves the ownership of the social media platform to be reached by April 5.
Reuters reported last week that White House-led talks among investors were coalescing around a plan for the biggest non-Chinese backers of ByteDance to increase their stakes and acquire the video app's US operations, according to two sources familiar with the discussions.
The future of the app used by almost half of all Americans has been up in the air since a law, passed with overwhelming bipartisan support, required ByteDance to divest TikTok by January 19.
The app briefly went dark in January after the US Supreme Court upheld the ban, but flickered back to life days later once Trump took office.
Trump quickly issued an executive order postponing enforcement of the law to April 5 and said in February he could further extend that deadline to give himself time to shepherd a deal.
