Luhut Pandjaitan, who has been leading the talks with Tesla, declined to disclose further details, citing a non-disclosure agreement.
Bloomberg News also reported that the Indonesia talks include plans for production facilities and to facilitate the company's supply chain, citing people familiar with the matter.
"I can't comment, we're still talking," Luhut told Reuters, adding that he had just recently held another round of talks with Tesla.
Tesla currently makes its electric cars in China's Shanghai, Germany's Berlin, and Austin and Fremont in the United States.
Indonesian authorities have said Japanese firms Toyota Motor Corp (7203.T) and Mitsubishi Motors Corp (7211.T) have pledged investments in EV production.
