The mass internment of Uyghurs and other Turkic Muslims in the camps has become largest-scale arbitrary detention of ethnic and religious minorities since World War II.

Many media outlets have reported that hundreds of thousands of Uyghurs, as well as Kazakhs, Kyrgyz and other ethnic minorities, are held in the camps.Radio Free Asia, a news service funded by the US government, estimated in January 2018 that 120,000 members of the Uyghurs were being held in political re-education camps in Kashgar prefecture alone at the time. In 2018, local government authorities in Qira County expected to have almost 12,000 detainees in vocational camps and detention centres and some projects related to the centres outstripped budgetary limits.Reports of Uyghurs living or studying abroad being detained upon return to Xinjiang are common, which is thought to be connected to the re-education camps. Many living abroad have gone for years without being able to contact their family members still in Xinjiang, who may be detainees.

Uyghur political figure Rebiya Kadeer, who has been in exile since 2005, has had as many as 30 relatives detained or disappeared, including her sisters, brothers, children, grandchildren, and siblings, according to Amnesty International. It is unclear when they were taken away.

On 13 July 2018, Sayragul Sauytbay, an ethnic Kazakh Chinese national and former employee of the Chinese state, appeared in a court in the city of Zharkent, Kazakhstan for being accused of illegally crossing the border between the two countries. During the trial she talked about her forced work at a re-education camp for 2,500 ethnic Kazakhs. Her lawyer argued that if she is extradited to China, she would face the death penalty for exposing re-education camps in Kazakh court.Her testimony for the re-education camps have become the focus of a court case in Kazakhstan,which is also testing the country's ties with Beijing. On 1 August 2018, Sauytbay was released with a six-month suspended sentence and directed to regularly check-in with police. She applied for asylum in Kazakhstan to avoid deportation to China.Kazakhstan refused her application. On 2 June 2019 she flew to Sweden where she was subsequently granted political asylum.

According to a Radio Free Asia interview with an officer at the Onsu County police station, as of August 2018, 30,000 persons, or about one in six Uyghurs in the county (approximately 16% of the overall population of the county), were detained in re-education camps.

Gene Bunin created the Xinjiang Victims Database to collect public testimonies on people detained in the camps. Each page lists basic demographic information including dates and suspected cause of detention, location, in addition to supplementary videos, photos and documents.

Writing in the Journal of Political Risk in July 2019, independent researcher Adrian Zenz estimated an upper speculative limit to the number of people detained in Xinjiang re-education camps at 1.5 million. In November 2019, Adrian Zenz estimated that the number of internment camps in Xinjiang had surpassed 1,000.In November 2019, George Friedman estimated that 1 in 10 Uyghurs are being detained in re-education camps.

When the BBC was invited to the camps in June 2019, officials there told them the detainees were "almost criminals" who could choose "between a judicial hearing or education in the de-extremification facilities".The Globe and Mail reported in September 2019 that some Han Chinese and Christian Uyghurs in Xinjiang who had disputes with local authorities or expressed politically unwelcome thoughts had also been sent to the camps.

Anonymous drone footage posted on YouTube in September 2019 showed kneeling blindfolded inmates that an analyst at the Australian Strategic Policy Institute said may have been an inmate transfer at a train station near Korla and may have been from a re-education camp.

Anar Sabit, an ethnic Kazakh from Kuytun living in Canada who was imprisoned in 2017 after returning home following the death of her father, was detained for having gone abroad. She found other minorities were interned for offenses such as using forbidden technology (WhatsApp, a V.P.N.), travelling abroad, but that even a Uyghur working for the Communist party as a propagandist could be interned for the offense of having been booked in a hotel by an airline with others who were under suspicion.

According to an anonymous Uyghur local government employee quoted in an article by US government-sponsored Radio Free Asia, during Ramadan 2020 (23 April to 23 May), residents of Makit County (Maigaiti), Kashgar Prefecture were told they could face punishment for religious fasting including being sent to a re-education camp.

According to a Human Rights Watch report published in January 2021, the official figure of people put through this system is 1.3 million.

Waterboarding, mass rape, and sexual abuse are reported to be among the forms of torture used as part of the indoctrination process at the camps.

Testimonies about treatment

Officially, the camps are known as Vocational Education and Training Centers, informally as "schools", and described by some officials as "hospitals" where inmates are treated for the "disease" of "extremist ideology". According to interment officials quoted in Xinjiang Daily, (a Communist Party-run newspaper) while "requirements for our students" are "strict ... we have a gentle attitude, and put our hearts into treating them". Being in one "is actually like staying at a boarding school."The newspaper quoted a former inmates as stating during his internment he had realized he had been "increasingly drifting away from 'home,'" under the influence of extremism. "With the government's help and education, I've returned. ... "our lives are improving every day. No matter who you are, first and foremost you are a Chinese citizen.'"  Testimonies in non-Communist Party literature from freed inmates have been considerably different.

Kayrat Samarkand, a Kazakh citizen who migrated from Xinjiang, was detained in one of the internment camps in the region for three months for visiting neighboring Kazakhstan. On 15 February 2018, Kazakh Foreign Minister Kairat Abdrakhmanov sent a diplomatic note to the Chinese Foreign Ministry, the same day as Kayrat Samarkand was freed from custody.After his release, Samarkand said that he faced endless brainwashing and humiliation, and that he was forced to study communist propaganda for hours every day and chant slogans giving thanks and wishing for a long life to Xi Jinping.

Mihrigul Tursun, an Uyghur woman detained in China, after escaping one of these camps, talked of beatings and torture. After moving to Egypt, she traveled to China in 2015 to spend time with her family and was immediately detained and separated from her infant children. When Tursun was released three months later, one of the triplets had died and the other two had developed health problems. Tursun said the children had been operated on. She was arrested for the second time about two years later. Several months later, she was detained the third time and spent three months in a cramped prison cell with 60 other women, having to sleep in turns, use the toilet in front of security cameras and sing songs praising the Chinese Communist Party.

Tursun said she and other inmates were forced to take unknown medication, including pills that made them faint and a white liquid that caused bleeding in some women and loss of menstruation in others. Tursun said nine women from her cell died during her three months there. One day, Tursun recalled, she was led into a room and placed in a high chair, and her legs and arms were locked in place. "The authorities put a helmet-like thing on my head, and each time I was electrocuted, my whole body would shake violently and I would feel the pain in my veins," Tursun said in a statement read by a translator. "I don't remember the rest. White foam came out of my mouth, and I began to lose consciousness," Tursun said. "The last word I heard them saying is that you being an Uyghur is a crime." She was eventually released so that she could take her children to Egypt, but she was ordered to return to China. Once in Cairo, Tursun contacted U.S. authorities and, in September, went to the United States and settled in Virginia. China's Foreign Ministry Spokesperson Hua Chunying has stated that Tursun was taken into custody by police on "suspicion of inciting ethnic hatred and discrimination" for a period lasting 20 days, but denies that Tursun was detained in a re-education camp.
Former inmates say that they are required to learn to sing the national anthem of China and communist songs. Punishments, like being placed in handcuffs for hours, waterboarding, or being strapped to "tiger chair" (a metal contraption) for long periods of time, are allegedly used on those who fail to follow.

Anar Sabit, a cooperative inmate who had a relatively minor offense of foreign travel, described her confinement in the women's section as prison-like and marked by bureaucratic rigidity but said that she was not beaten or tortured .[86] Before and after her internment, Sabit said that she experienced what Chinese sometimes call gui da qiang, or 'ghost walls' "that confuse and entrap travelers".After her release from internment, she said that she remains a "focus person" in her hometown of Kuytun where she lives with her uncle's family. She described the town as resembling an "open air prison" due to the careful monitoring by cameras, sensors, police, and the neighborhood residential committee, and that she feels shunned by almost all friends and family and worries that she will endanger anyone who helps her. After Sabit moved out of her uncle's house, Sabit lived in the dormitory of the neighborhood residential committee who she said threatened to return her to the internment camp for speaking out of turn.

According to detainees, they were also forced to drink alcohol and eat pork, which are forbidden in Islam.Some reportedly received unknown medicines while others attempted suicide. There have also been deaths reported due to unspecified causes.Detainees have alleged widespread sexual abuse, including forced abortions, forced use of contraceptive devices and compulsory sterilization. It has been reported that Han officials have been assigned to reside in the homes of Uyghurs who are in the camps. Rushan Abbas of the Campaign for Uyghurs argues that the actions of the Chinese government amount to genocide according to United Nations definitions which are laid out in the Genocide Convention.

According to Time, Sarsenbek Akaruli, 45, a veterinarian and trader from Ili, Xinjiang, was arrested in Xinjiang on 2 November 2017. As of November 2019, he is still in a detention camp. According to his wife Gulnur Kosdaulet, Akaruli was put in the camp after police found the banned messaging app WhatsApp on his cell phone. Kosdaulet, a citizen of neighboring Kazakhstan, has traveled to Xinjiang on four occasions to search for her husband but could not get help from friends in the Chinese Communist Party. Kosdaulet said of her friends, "Nobody wanted to risk being recorded on security cameras talking to me in case they ended up in the camps themselves."

In May to June 2017, a woman native to Maralbexi County (Bachu) named Mailikemu Maimati (also spelled Mamiti) was detained in the county's re-education camp according to her husband Mirza Imran Baig. He said that after her release, she and their young son were not given their passports by Chinese authorities.

According to Time, former prisoner Bakitali Nur, 47, native of Khorgos, Xinjiang on the Sino-Kazakh border, was arrested because authorities were suspicious of his frequent trips abroad. He reported spending a year in a cell with seven other prisoners. The prisoners sat on stools seventeen hours a day, were not allowed to talk or move and were under constant surveillance. Movement carried the punishment of being put into stress positions for hours. After release, he was forced to make daily self-criticisms, report on his plans and work for negligible payment in government factories. In May 2019, he escaped to Kazakhstan. Nur summarized his experience in jail and under constant monitoring after his release saying, "The entire system is designed to suppress us."

According to Radio Free Asia, Ghalipjan, a 35 year old Uyghur man from Shanshan/Pichan County who was married and had a five-year-old son, died in a re-education camp on 21 August 2018. Authorities reported his death was due to heart attack, but the head of the Ayagh neighborhood committee said that he was beaten to death by a police officer. His family was not allowed to carry out Islamic funeral rites.

According to the Xinjiang Police Files, Chen Quanguo issued a shooting order for detainees attempting to escape in 2018.

In June 2018, President of the World Uyghur Congress (WUC) Dolkun Isa was told that his mother Ayhan Memet, 78, had died two months earlier while in detention at a "political re-education camp".[The WUC president was unsure if she had been incarcerated in one of the many "political re-education camps".

According to a 2018 report in the New York Times, Abdusalam Muhemet, 41, who ran a restaurant in Hotan before fleeing China in 2018, said he spent seven months in prison and more than two months in a camp in Hotan in 2015 without ever being criminally charged. Muhemet said that on most days, the inmates at the camp would assemble to hear long lectures by officials who warned them not to embrace Islamic radicalism, support Uyghur independence or defy the Communist Party.

In an interview with Radio Free Asia, an officer at the Kuqa (Kuchar, Kuche) County Police Department reported that from June to December 2018, 150 people at the No. 1 Internment Camp in the Yengisher district of Kuqa county had died, corroborating earlier reports attributed to Himit Qari, former area police chief.

In August 2020, the BBC released texts and a video smuggled out of a re-education camp by Merdan Ghappar, a former model of Uyghur heritage. Mergan had been allowed access to personal effects, and used a phone to take videos of the camp he is interned in.

In February 2021, the BBC issued further eyewitness accounts of mass rape and torture in the camps.

Forced labor

Adrian Zenz reported that the re-education camps also function as forced labor camps in which Uyghurs and Kazakhs produce various products for export, especially those made from cotton grown in Xinjiang. The growing of cotton is central to the industry of the region as "43 percent of Xinjiang's exports are apparel, footwear, or textiles". In 2018, 84% of China's cotton was produced in the Xinjiang province. Since cotton is grown and processed into textiles in Xinjiang, a November 2019 article from The Diplomat said that "the risk of forced labor exists at multiple steps in the creation of a product".

In 2018, the Financial Times reported that the Yutian / Keriya county vocational training centre, among the largest of the Xinjiang re-education camps, had opened a forced labour facility including eight factories spanning shoemaking, mobile phone assembly and tea packaging, giving a base monthly salary of ¥1,500 RMB. Between 2016 and 2018, the centre expanded 269 percent in total area.

The Australian Strategic Policy Institute reported that from 2017 to 2019 more than 80,000 Uyghurs were shipped elsewhere in China for factory jobs that "strongly suggest forced labour".Conditions of these factories were consistent with the stipulations of forced labor as defined by the International Labor Organization.

In 2021, former supplier for Nike, Esquel Group, sued the United States Government for listing it on a sanction list for forced labor allegations in Xinjiang. It was later removed from the sanction list due to lack of evidence provided by the US Commerce department.

In October 2021, the CBC in collaboration with the Investigative Reporting Project Italy along with The Guardian reported on the export of tomato products from Xinjiang and tied to forced labor by the Uyghurs. The report identified tomato products being exported to other countries such as Italy to be repackaged for sale in other markets such as Canada.

In June 2021, human rights reports indicated that costs of solar modules had been depressed in recent years due to Chinese forced labor practices in the solar module and wind turbine exports industry. Globally, China dominated manufacturing, installation and exports in the field.The practice of forced labor was blamed for the bankruptcy of firms in the US and German solar industries, multiple times, over the decade 2010–2020.In one report, upon declaring a bankruptcy, the cost of raw materials for manufacturing panels was suggested to be 30% of the total manufacturing costs. It was argued that China do not pay labor costs.
