Boris Johnson has said there will "effectively be a diplomatic boycott" of the Winter Olympics in Beijing given that no UK ministers or officials will be attending.
Conservative former leader Iain Duncan Smith begged the Prime Minister to ensure the UK follows the lead of the United States by having a full diplomatic boycott of the Games in February.
Mr Johnson said the Government has "no hesitation" in raising concerns over human rights abuses with China, adding in the Commons: "There will be effectively a diplomatic boycott of the Winter Olympics in Beijing.
"No ministers are expected to attend and no officials.
"What I can tell the House is I don't think sporting boycotts are sensible and that remains the policy of the Government."
Australia Prime Minister Scott Morrison has confirmed they will not send officials to February's Olympics, joining a US diplomatic boycott of the Games.
Canberra's decision comes amid "disagreement" with China over a slew of issues that have plunged relations into the most serious crisis since the Tiananmen Square crackdown in 1989.
Mr Morrison also cited human rights abuses in Xinjiang and Beijing's freeze on ministerial contact with Australia.
"Australia will not step back from the strong position we've had standing up for Australia's interests and obviously it is of no surprise that we wouldn't be sending Australian officials to those Games," Mr Morrison said.
The decision, which stopped short of preventing athletes from attending the 2022 Olympics, comes a day after the United States announced its diplomatic boycott.
The US decision was taken over what Washington termed China's genocide of the Uyghur minority in the Xinjiang region and other human rights abuses, prompting Beijing to warn the US would "pay the price".
China's initial response to Australia following suit was more muted.
A spokesperson for the Chinese Embassy in Canberra said it "runs counter to its (Canberra's) publicly pronounced expectation to improve China-Australia relations".
But rights groups welcomed the move, with Human Rights Watch China director Sophie Richardson calling it a "crucial step toward challenging the Chinese government's crimes against humanity targeting Uyghurs and other Turkic communities".
Campaigners say that at least one million Uyghurs and other Turkic-speaking, mostly Muslim minorities have been incarcerated in camps in Xinjiang, where China is also accused of forcibly sterilising women and imposing forced labour.
Beijing has defended the camps as vocational training centres aimed at reducing the appeal of Islamic extremism.
Australia's ties with China have been in freefall in recent years, with Beijing introducing a raft of punitive sanctions on Australian goods.
China has been angered at Australia's willingness to legislate against overseas influence operations, to bar Huawei from 5G contracts and call for an independent investigation into the origins of the coronavirus pandemic.
Australia's recent move to equip its navy with nuclear-powered submarines under a new defence pact with Britain and the United States - widely seen as an attempt to counter Chinese influence in the Pacific region -
further infuriated Beijing.
At least two Australians are currently being detained in China, with journalist Cheng Lei held for more than a year and academic Yang Jun on trial for espionage.
Mr Morrison said Canberra had "always been open" to talks with Beijing, but those attempts had been rebuffed.
"There's been no obstacle to that occurring on our side, but the Chinese government has consistently not accepted those opportunities for us to meet about these issues," he said.
"Australia's a great sporting nation and I very much separate the issues of sport and these other political issues. They're issues between two governments, and I would like to see those issues resolved."
The Chinese Embassy spokesperson signalled Australian athletes would be welcome at the Games, wishing them an "excellent performance".
"Australia's success at the Beijing Winter Olympics depends on the performance of Australian athletes, not on the attendance of Australian officials, and the political posturing by some Australian politicians," the spokesperson said.
The Australian Olympic Committee (AOC) said it would not impact the team's preparations.
"The AOC is very focused on ensuring that team members are able to safely travel to China given the complexity of the Covid environment, with our athletes departing from overseas locations," AOC chief executive Matt Carroll said.
"Getting the athletes to Beijing safely, competing safely and bringing them home safely remains our greatest challenge."
About 40 Australian athletes are expected to compete in the Beijing Games, which open on 4 February, with AOC support staff accompanying them.
