Foreign Ministry spokeswoman Hua Chunying said the request had been passed to Trump's transition team and to the current administration of Barack Obama.
"We urge the US side once again not to allow the Taiwan administration to send the so-called delegation to attend the inauguration and to avoid any forms of official exchange with Taiwan," Hua said at a daily briefing.
China firmly opposes "anyone from the Taiwan administration engaged in activities that interfere or undermine the China-US relationship in the US under any pretext," she said.
Along with attending the inauguration, the delegates plan to hold talks with politicians, academics and overseas Chinese community representatives.

Trump angered Beijing and upset decades of diplomatic precedent by talking by phone with Taiwanese President Tsai Ing-wen shortly after winning November's presidential election.

Tensions across the Taiwan Strait have risen since Tsai's election last year, with Beijing cutting off contacts and working to deepen Taiwan's diplomatic isolation.
