Trump made the comments in an interview aired on Fox News on Monday.
"Yeah ... I have talked to him and I have talked to his people, too," Trump said when asked if he has spoken to the Chinese leader since the U.S. president's inauguration.
"We have a very good personal relationship," Trump added.
The president did not provide details on when exactly the call happened or what was discussed.
The White House and the Chinese foreign ministry did not immediately respond to a request for comment on Trump's interview to Fox News.
Trump and Xi had spoken just before Trump took office in January and discussed issues including TikTok, trade and Taiwan.
China imposed targeted tariffs on U.S. imports last week and put several companies, including Alphabet's (GOOGL.O) Google, on notice for possible sanctions, in a measured response to Trump's across-the-board 10% duties, which had come on top of prior tariffs.
Washington and Beijing have had tense relations for years over differences ranging from trade tariffs and cybersecurity to Taiwan, Hong Kong, human rights and the origins of COVID-19.
