Biden’s time in office did see flare-ups in relations with China, including a spy balloon saga and displays of Chinese military firepower around Taiwan triggered by the visit of a senior US official.
China says its claim to the self-ruling island is a red line.
However, the Biden administration aimed to “responsibly manage” rivalry with Beijing after Trump’s first term.
Beijing is likely to be most concerned about the president-elect’s unpredictability, analysts say.
“The Chinese are ready to negotiate and deal, and probably hope for early engagement with the Trump team to discuss potential transactions,” said Bonnie Glaser, managing director of the German Marshall Fund’s Indo-Pacific Program.
“At the same time, however, they are ready to retaliate if Trump insists on imposing higher tariffs on China.”
She added that China may also be “likely worried that that they lack reliable back channels to influence Trump’s policy”.
Biden on Saturday acknowledged there had always been disagreements with Xi but added that discussions between him and the Chinese leader had been “frank” and “candid”.
The pair held three face-to-face meetings during Biden’s time in the White House, including a key summit last year in San Francisco where both sides came to agreements on combatting narcotics and climate change.
But Biden’s White House also continued Trump-era tariffs. His government imposed duties in May targeting China’s electric cars, solar panels and steels.
He also strengthened defence alliances across Asia and the Pacific to counter China’s increasing assertiveness in the region. The outgoing president has also said the US would defend Taiwan if it were invaded by China.
