Thousands of Chinese basketball fans cheered on the Los Angeles Lakers and Brooklyn Nets at an NBA exhibition game in the city of Shenzhen on Saturday night - but some warned the organisation to stay out of politics. Daryl Morey, general manager of another team, the Houston Rockets, voiced support for pro-democracy protests in Hong Kong in a tweet last week, prompting Chinese sponsors and partners to cut ties with the NBA. China is estimated to be worth more than $4 billion for the NBA, so the stakes are high.
