Fears are growing in Washington DC among politicians about the risks posed by AI technology on humans and property.
Earlier this month, former Anthropic researcher Jacob Coxon said that "people building AI earnestly believe that it could kill us all by the end of the decade".
Trump has repeatedly downplayed concerns about AI and argued that additional regulation is unnecessary.
"We will not in any way hinder or stifle the Growth of this incredible Industry," Trump wrote on Truth Social.
"Rather, we will cherish it, help it, and watch over it, as it grows! However, we will also be looking for BAD, and we can do that, very easily, with our already existing Criminal and Civil Justice System."
If Trump follows through on the pledge, it would be his second AI czar.
Venture capitalist David Sacks previously served in the role before stepping down in the northern hemisphere spring and moving into an external advisory position.
Sacks has echoed Trump's scepticism of new AI regulation.
Speaking at a Politico event on Wednesday, he said AI developers should be responsible for ensuring the safety of their products and could be held liable if problems arise, adding that new federal rules are unnecessary.
Trump's post comes ahead of his scheduled meeting with Chinese President Xi Jinping on Thursday.
The US and China are competing for leadership in artificial intelligence, which both governments view as vital to their economic and military strength.
Trump and technology executives have argued that excessive regulation would undermine US companies' ability to compete with Chinese rivals, a claim that safety advocates often reject.
US Treasury Secretary Scott Bessent will meet with Chinese Vice Premier He Lifeng on Sunday at JPMorgan Chase headquarters in New York to discuss AI security, trade and other economic issues, a person familiar with the planning said on Saturday.
