A company founded by Erik Prince has reportedly agreed to build a training center in Xinjiang, China, where one million Uighurs and members of other mostly Muslim minority groups are being held in detention camps. Prince is the founder of Blackwater, a former Navy SEAL, and the brother of Education Secretary Betsy DeVos. He has been interviewed as part of the Mueller probe after reports that he helped establish an alleged backchannel to Russia for the Trump administration. His company, Frontier Services Group, provides security and logistics for businesses in dangerous regions. It posted a statement on its website saying it had signed a deal to build a training center in Xinjiang. However, a Prince spokesman told Reuters on Friday that he had “no knowledge or involvement whatsoever with this preliminary memorandum regarding the company’s activity in Xinjiang” and a Hong Kong-based spokesman for Frontier said the statement was “published in error by a staff member in Beijing” and had been removed. The statement said a signing ceremony took place in Beijing this month, and that the company will invest 4 million yuan ($600,000) in the center. It’s not known what kind of training will be carried out.
