China's official basketball association says it has decided to suspend exchanges and cooperation with the Houston Rockets following a tweet by the team's general manager in support of the so-called pro-democracy protesters in Hong Kong.

The Chinese Basketball Association (CBA), chaired by Yao Ming, said Sunday on its Weibo account that Daryl Morey had made "improper remarks regarding Hong Kong" to which it expressed its "strong opposition."

China Central Television's sports channel also announced that it has decided to suspend cooperation and exchanges with Houston Rockets including broadcasting.
