China has condemned a planned US diplomatic boycott of the 2022 Winter Olympics in Beijing and threatened to retaliate.
Foreign ministry spokesman Zhao Lijian said China would take "resolute counter-measures", but did not give further details.
On Monday, the US said it would not send diplomats to Beijing over concerns about China's human rights record.
It added that US athletes could go and would have full government support.
At a media briefing on Tuesday, Mr Zhao accused the US of violating "political neutrality in sport" and said the proposed boycott was "based on lies and rumours".
Tensions are high between both countries. The US has accused China of genocide in its repression of the predominantly Muslim Uyghur minority in the western region of Xinjiang - an allegation China has strongly denied.
Relations are also strained over China's suppression of political freedoms in Hong Kong, and because of concerns for the Chinese tennis player Peng Shuai, who was not seen for weeks after she accused a top government official of assault.
The Women's Tennis Association last week suspended all tournaments in China because of "serious doubts" about Ms Peng's safety.
'Political posturing'
High-level government representatives - from the US and other countries - are usually present at Olympic Games. Earlier this year, First Lady Jill Biden led the US delegation at the summer Olympics held in Tokyo.
But on Monday, White House Press Secretary Jen Psaki said the US would not contribute to the "fanfare" of the Olympics. She said not sending an official delegation to the 2022 Games "could send a clear message".
"US diplomatic or official representation would treat these games as business as usual in the face of... egregious human rights abuses and atrocities in Xinjiang," she said. "We simply can't do that."
However, Ms Psaki added the US government did not feel it was right "to penalise athletes who had been training for this moment".
On Chinese social media platform Weibo, the search topic "US diplomatic boycott of Beijing Winter Olympics" was censored as of Tuesday morning.
Most of the comments below a post on the announcement by state media outlet Global Times were also deleted, leaving only eight out of close to 1,500 comments untouched.
"The Olympics are for athletes, what does it have to do with... politicians? Even if you boycott, the only people you're hurting are your own countrymen (including athletes)," one such comment read.

China had pre-emptively tried to take the sting out of this in the last few days by dismissing such a move as irrelevant.
Officials said Covid restrictions meant Beijing and the IOC weren't inviting any dignitaries anyway. You can expect to see this decision derided as yet another sign of a "Cold War mentality".
But it was always very unlikely that US President Joe Biden or any senior political figure would come to games hosted by a government he said is committing genocide.
In the months building up to this decision, one senior US diplomat I spoke to said they'd try to educate their athletes about what's happening in Xinjiang and Hong Kong. They envisaged something like "fireside chats" among athletes between events in Beijing.
Will the UK now follow suit? London does not officially accuse Chinese President Xi Jinping's Communist regime of genocide, but Foreign Secretary Liz Truss has reportedly said just that in private conversations.
Some months ago, a senior UK official, intimately involved in policy on China, told me they thought the UK would be seen as America's "poodle" if it joined
