Beijing Winter Olympics boycott: Why are the Games so controversial?
Beijing Winter Olympics and Paralympics are taking place over the coming weeks.
China's human rights record has led some countries to declare diplomatic boycotts of the Games, which means their top officials won't attend. 
Winter Olympics take place from 4 February to 20 February, with about 3,000 athletes competing in 109 different events.
Winter Paralympics run from 4 March to 13 March, with about 750 competitors across 78 events.
China's government and businesses are spending $3.9bn (£2.95bn) on the Games, which are taking place in and around Beijing:
About 1.2 million cubic metres of artificial snow is being used because so little falls in the region. China has been criticised over the environmental impact. 
Because of Covid, competitors and officials are in secure "bubbles" and no spectator tickets have been sold to the public.
US, UK and Canada declared a diplomatic boycott, along with India, Australia, Lithuania, Kosovo, Belgium, Denmark and Estonia.
, but no ministers or officials are attending.
US said this was because of China's "human rights abuses and atrocities in Xinjiang" - against the province's Muslim population.
British MP Iain Duncan Smith, who represents the Inter-Parliamentary Alliance on China, said: "The Chinese government commits industrial-scale human rights abuses in the Uyghur Region, Tibet and sends near-daily military incursions into Taiwan's airspace. 
"We cannot lend any legitimacy to China's despotic regime."
India declared a diplomatic boycott because one of the torchbearers was a Chinese army officer involved in a deadly skirmish with its troops on the border between the two countries. 
Japan has also said it isn't sending ministers to the Games, but it is sending Olympic officials. 
New Zealand, Austria, Slovenia, Sweden and the Netherlands are not sending government representatives, but say Covid is their reason.
France has been against a boycott. President Macron has said: "I don't think we should politicise these topics, especially if it is to take steps that are insignificant and symbolic." 
re have also been protests across the world against the Beijing Games by human rights activists.
Beijing government is accused of committing atrocities against the Uyghur Muslim population in the northwest province of Xinjiang. 
Human rights groups believe more than one million Uyghurs have been detained over the past few years in a large network of what the state calls "re-education camps", with hundreds of thousands sentenced to prison terms.
re is evidence that Uyghurs are being used as forced labour, and women are being forcibly sterilised. Some former camp detainees allege they were tortured and sexually abused.
Beijing is also accused of restricting the freedom of people in Hong Kong through new legislation including the Hong Kong National Security Law.
In its 2021 annual report, Human Rights Watch said that "Beijing's repression - insisting on political loyalty to the Chinese Communist Party - deepened across the country".
China has consistently denied violating human rights in Xinjiang, and has warned its most vocal accusers - such as the US and Germany - not to interfere in its "internal affairs" in Hong Kong.
It has spoken out most loudly against the US diplomatic boycott. 
China's Foreign Ministry said that the US had "clearly violated the Olympic spirit", and "will pay a price for its erroneous actions". However, it has not specified what this price might be.
Athletes and others attending the Games are being warned about security weaknesses in the app they have to use for daily Covid monitoring.
Cybersecurity group Citizen Lab said the app has weak encryption systems and that data loaded on it such as medical and travel histories could be exploited by hackers. 
Several countries have reportedly told athletes to leave their main devices at home and use burner phones at the Games.
Chinese state media have dismissed the concerns.
