Chinese state media slam U.S. basketball's NBA in free speech row

National Basketball Association (NBA) of endorsing violence and peddling a "secessionist pipe dream" as a row escalates over comments by a leading team official in support of protests in Hong Kong.

Houston Rockets general manager Daryl Morey apologised on Monday for a Twitter post over the weekend backing the Hong Kong protest. The comment, which was quickly deleted, sparked anger in China, and broadcasters, sportswear companies and sponsors said they would review their relationship with the league.

The NBA initially described the anger over the message as "regrettable", but Commissioner Adam Silver told a news conference in Japan on Tuesday that it was not up to the NBA to regulate what players, employees and team owners said.

On Wednesday, an editorial in the official English-language China Daily accused Silver of "brazenly endorsing Morey's secessionist-supporting tweet" and giving "a shot to the arms of the rioters of Hong Kong".

It said, "If Silver thinks endorsing the indiscriminate violence the radical Hong Kong protesters are resorting to...is supporting freedom of expression, then he should think again."

The protests were "a bid to liberate the city" and "a secessionist pipe-dream" peddled by demonstrators "to justify their summer hooliganism", it added.

The state-owned Global Times tabloid accused Silver of caving in to political pressure, saying the NBA was treating the Chinese market with arrogant disregard.

"Tweeting something offensive to the Chinese people before a series of NBA promotional activities in China only shows a lack of intellect, respect, and responsibility," it said.

Chinese state television has already cancelled plans to air exhibition games played in China this week, saying in a statement that a country's sovereignty and social stability were "not within the scope of freedom of speech".

China has accused Western governments of stirring up anti-Beijing sentiment in Hong Kong, which has been roiled by months of sometimes violent protest. (Reporting by David Stanway; Editing by Clarence Fernandez)
