China is confirming plans to prosecute three Australians working for a casino operator who were detained last month.

Chinese foreign ministry spokesman Geng Shuang said Wednesday that the three employees of Crown Resorts Ltd. would have their cases handled "in accordance with law." Geng did not offer details on the allegations they face.

Australia's foreign ministry said Tuesday that it had received formal arrest notices from the Chinese side.

Casino gambling is illegal in mainland China and agents are banned from organizing groups of more than 10 Chinese citizens to gamble abroad. According to Chinese law, anyone who "runs a gambling house or makes gambling his profession" can face up to three years in prison.

Crown Resorts did not return messages seeking comment on Tuesday and Wednesday.
