The NBA has terminated its relationship with a Chinese-based basketball academy located in the controversial region of Xinjiang,
according to a letter league executives sent to a U.S. senator. Sports Illustrated has obtained a copy of the letter, sent on Tuesday to Sen. Marsha Blackburn (R-Tenn.). The note was a response to a June 30th letter Blackburn penned to NBA commissioner Adam Silver over her concerns regarding the league’s relationship with the communist country. In the NBA’s response, Mark Tatum, the association’s deputy commissioner and chief operating officer, answers three questions that Blackburn posed in her June letter, including one about the operation of a training center in Xinjiang, known as one of the world’s worst humanitarian zones.
