Kyrie Irving acknowledged he was "conflicted" but would not divulge discussions with commissioner Adam Silver as the NBA's relationship with China remains on the agenda.

Preseason games in China - involving Irving's Brooklyn Nets - were at the centre of controversy after a since-deleted tweet from Houston Rockets GM Daryl Morey supported anti-government protesters in Hong Kong.

Morey's comments overshadowed what had been expected to be a celebration of the NBA in one of their key international markets, with media duties cancelled, although the games went ahead.

LeBron James, whose Los Angeles Lakers were also involved, weighed in on his return to the United States, suggesting Morey "wasn't educated" on the matter.

And Irving was asked about the situation following the Nets' final preseason game against the Toronto Raptors at Barclays Center, where fans were pictured wearing "Stand with Hong Kong" shirts in the stands.

Questions centred on a reported behind-closed-doors meeting between Silver and the players involved in China.

"I don't know whose notes [reports are from] or who is in there that you can't really depend on to keep a conversation like that in house," Irving said. "Especially when it is about the NBA brand and the NBA players being impacted by it.

"I stand for four things, man: inner peace, freedom, equality and world peace. So, if that is being conflicted inside of me, I am definitely going to have something to say, and I left it in that room."

Irving, who scored 19 points on 7-of-17 shooting in the defeat to the Raptors, added: "I understand that Hong Kong and China is dealing with their issues, respectively.

"But there is enough oppression and stuff going on in America for me not to be involved in the community issues here as well."

Silver claimed earlier this week the Chinese government had asked the NBA to fire Morey, adding: "We said there's no chance that's happening. There's no chance we'll even discipline him."
