The general manager of the NBA Houston Rockets team, Daryl Morey, has embroiled himself in trouble due to his tweet on last Friday supporting Hong Kong's protests. Some Chinese companies spoke out about the matter even before officials.

Shanghai Pudong Development Bank Credit Card Center was the first to do so, saying on Sunday that it "opposes and protests against" Morey's "erroneous" remarks and has suspended all marketing and publicity activities related to the Rockets.

Following the bank, sports brand Li Ning denounced the post and said it had stopped all forms of cooperation with the Rockets. Meanwhile, Shanghai Jiayin Finance Technology notified the Rockets that all partnerships between the two sides have been halted.

Tencent Sports, which signed a five-year, 1.5-billion-U.S.-dollar deal with the NBA in July, announced that all live streaming and news reporting of the Rockets will be suspended. It also gave customers, who bought a subscription to watch the Rockets games online, a chance to opt for another team.

As of October 8, 11 out of 25 NBA's official partners in China have announced they would suspend ties with the NBA, including ANTA Sports, Starbuck's China rival Luckin Coffee, smartphone maker Vivo, travel service provider Ctrip and Mengniu Dairy. 

Morey's tweet, "Fight for Freedom. Stand with Hong Kong," was quickly deleted last Friday, but not before it generated huge controversy in China. China's consulate general in Houston urged the team to "clarify and immediately correct the mistakes" in a statement last Sunday. Beijing repeatedly said that some protesters in Hong Kong were mobs and rioters, instead of the so-called "peaceful pro-democracy protesters" described by the Western media.

However, the NBA Commissioner Adam Silver released a statement Tuesday on how NBA will not "put itself in a position of regulating what players, employees and team owners say or will not say on these issues," concerning Morey's improper remarks.

On the same day, China Central Television (CCTV) Sports channel of China Media Group (CMG) announced that it will suspend its NBA broadcasts because Silver supported improper remarks. Before that, the Chinese Basketball Association (CBA) had already announced the termination of cooperation with Houston Rockets.

Basketball is one of the most popular sports in China. Here are some facts and figures showing how vital China and its 500-million-fan base is to the NBA.

The NBA has had a presence in China for almost three decades. It now has relationships with a number of television and digital media outlets throughout China, including a long-standing partnership with CCTV.

The Houston Rockets is widely followed especially in China. That's because the franchise drafted Chinese player Yao Ming in 2002. The eight-time NBA All-Star was inducted into the Basketball Hall of Fame in 2016.

NBA China was launched in 2008. Seventeen NBA teams have played 26 games in Beijing, Guangzhou, Macao, Shanghai, Shenzhen and Taipei in the past five years. NBA China alone is now worth over 4 billion U.S. dollars, according to Forbes.
