Chinese citizens are not banned from playing golf. Communist Party members are banned from joining golf clubs. Plus fwiw I believe Dr Ruayrungruang holds Thai citizenship too.
Adam, maybe a bit of a flippant remark by me apparently. I would imagine however that anyone on the board of a big Chinese company is almost certainly a party member. Also I doubt Dr. Ruayrungruang's Thai citizenship is of any relevance to the Chinese when it comes to party directives.
As I said, my comment was meant as an ironic joke rather than a serious point hence the emoticon.
