Mark Allen was recently fined £1,000 for comments made in China during the Haikou World Open last month, and now faces further action.
WPBSA Chairman Jason Ferguson said: "The WPBSA is responsible for the governance of snooker worldwide and takes very seriously comments made which could be perceived to be directed at a particular nation. The Chairman of the disciplinary committee Nigel Mawer is making further inquiries into this incident. Mark Allen will be given 14 days to respond to the letter."
