China is urging the US not to allow a Taiwanese delegation to attend president-elect Donald Trump's inauguration.
Trump broke with decades of precedent in December by taking a congratulatory telephone call from Taiwan President Tsai Ing-wen, and he has said the "One China" policy was up for negotiation.
A Taiwan delegation, led by former premier and former ruling party leader Yu Shyi-Kun, and including a Taiwan national security adviser and some MPs, will attend Friday's inauguration, Taiwan's Foreign Ministry said this week.
It is typical for Taiwan to send a delegation to US presidential inaugurations at the invitation of the inaugural committee, which is made up of US congressmen.
A spokesman for Taiwan President Tsai Ing-wen's office said no meetings were scheduled with the new Trump administration while the delegation was there for the event.
Chinese foreign ministry spokeswoman Hua Chunying said China was opposed Taiwan using any excuse to send people to America to "engage in activities to interfere in or damage China US ties".
"We again urge the relevant side in the United States not to allow the Taiwan authority to send a so-called delegation to the United States to attend the presidential inauguration and not have any form of official contact with Taiwan," Hua told reporters at a regular press briefing.
"China's position has already accurately and unmistakably been given to the US administration and Trump's team," Hua said.
