UZYNAGHASH, Kazakhstan -- When Bikamal Kaken's husband vanished during a 2017 visit to Xinjiang, northwestern China, she had good reason to believe he would not be returning home to Kazakhstan anytime soon.
But she did not anticipate just how dire his fate was.
Rights groups at the time of Adilgazy Muqai's disappearance were sounding the alarm over a mushrooming network of facilities for the massive incarceration of mostly Muslim minority citizens in Xinjiang.
Kaken heard that her husband had fallen victim to the system. But three agonising years later, she learned he had met an even worse judgment: a nine-year prison sentence for extremist crimes.
"I am so worried. The Chinese [authorities] will destroy him in jail," Kaken, a Chinese-born ethnic Kazakh who is now a Kazakh citizen, told AFP through tears, pressing her two young daughters tightly to her body.
Beijing has rounded up more than 1 million people -- mostly Muslims from Turkic-speaking groups like Uighurs and Kazakhs -- on vague extremism and separatism pretexts in the Xinjiang region, rights groups say.
The sprawling network of detention centres are vocational "training" facilities used to counter extremism where attendance is voluntary, claims Beijing.
Yet in neighbouring Kazakhstan, 44-year-old Kaken is just one of a growing number of relatives to discover their missing family members are not in the centres as previously thought but instead are serving hard jail time.
'Full of lies'
Kaken and her husband, a retired oil worker, moved to Kazakhstan when she was pregnant with her youngest child, now three, after hearing reports that Xinjiang authorities were forcing women from minority groups to have abortions.
But 47-year-old Muqai, who had right of residency in Kazakhstan but was not a passport-holder, was lured back to his native region in May 2017 by his former employers.
The company pension that his family subsisted on could be cancelled if he failed to attend a meeting, they said.
When news of Muqai's sentence finally emerged three years after his disappearance, it came from an unlikely source -- a senior diplomat of the country that had jailed him.
Chinese Ambassador to Kazakhstan Zhang Xiao told a state-owned news outlet that Muqai was sentenced to nine years on extremism charges and in the same interview dismissed Kaken's account of her family's ordeal.
Her story was "full of lies, without a single sentence of truth", Zhang told the Global Times, a Chinese newspaper.
Kaken, who sews clothes and accepts charity to pay for a studio apartment in the provincial town of Uzynagash, about 60km from Almaty, insists her husband is innocent.
"His only crime is his Kazakh identity," she told AFP.
Chinese documents leaked in February to the New York Times showed that Xinjiang authorities were closely monitoring residents and were recording their backgrounds, religious habits and relationships, as well as various behaviours deemed "problematic".
Reasons for detention included applying for a passport, wearing a veil years ago and "clicking on a web-link and unintentionally landing on a foreign website", according to the documents.
'Few are truly free'
Despite close relations between the two governments, Kazakhstan has emerged as a hub for activism against Beijing's policies in Xinjiang, where thousands of Kazakhs have family ties.
In 2019, the Chinese regime began boasting that most citizens had "graduated" from the centres, after Kazakhstan said Beijing had allowed hundreds of ethnic Kazakhs with Kazakh residence permits to leave China and reunite with families across the border.
The video appeals and the media attention they attracted played a role in pressuring Beijing, many residents of Kazakhstan say.
Yet other Kazakhs began hearing their relatives had received jail sentences not long after this wave of releases, Mehmet Kasikci, a doctoral student at Arizona State University in the United States who volunteered with the group, told AFP.
"Yes, hundreds of thousands have probably been released from the camps, but few are truly free, and more importantly, hundreds of thousands have also been sent to official prisons," he told AFP.
Protests against the Chinese regime have continued.
About 200 protesters gathered in September in Almaty to demand that Beijing stop meddling in Kazakhstan's internal affairs and to demonstrate against the regime's abuses of ethnic minorities, including ethnic Kazakhs living in Xinjiang.
Baibolat Kunbolat was among those to record testimonies in the group's offices and write letters of appeal to the Kazakh government after hearing that his 30-year-old brother, Baimurat Nauryzbek, had been interned in one of the "training" centres.
But he first did so in late 2019, after others had already been campaigning for more than a year.
He held back at first out of respect for the "neighbourly relations" between Kazakhstan and China, he told AFP.
His brother's 10-year sentence for inciting racial hatred was confirmed to him in February by a member of the Chinese mission in Kazakhstan, Gu Ming, after Kunbolat resorted to picketing the consulate in Almaty to demand Nauryzbek's freedom.
Kumbolat's brother was convicted in 2018 over an internet forum post that he allegedly wrote in 2012 as well as over other posts, the diplomat told Kumbolat.
Gu informed Kunbolat that the embassy would "engage with the Kazakhstan government to have action taken against you" if Kunbolat continued his protests, which Gu said could negatively affect Nauryzbek's "reform".
The Chinese embassy ignored a request to confirm the correspondence via the WeChat messaging app, which Kunbolat showed to AFP.
"We waited almost a year [to raise Nauryzbek's case] because there were rumours that the maximum time in a camp is a year," Kunbolat said. "We deeply regret this now."
In September, an investigative report also detailed how Chinese authorities have destroyed nearly 16,000 mosques in Xinjiang in recent years as part of their efforts to root out Islamic culture from the Communist Party nation.
