What has happened to Crown Resorts in China?
* 18 Crown employees, including three Australians, detained in China in raids on October 13 and 14
* Detainees include senior Crown marketing executive, Jason O'Connor, who works in Crown's international "high roller" operations
Why have they been detained?
* The Crown employees are reportedly detained in relation to China's gambling and gambling promotion laws but no charges have been laid
* Gambling, and promotion of gambling, is illegal in mainland China, except for official lotteries
Where are Crown's casinos?
* Crown operates three casinos in Macau and one in Manila under the joint-venture Melco Crown Entertainment, and casinos in Melbourne and Perth
What is Australia doing about this?
* Crown has arranged legal representation for the detainees, and is trying to provide support to the families of the detainees in China and Australia
* Department of Foreign Affairs officials have visited two of the detained Australians and are seeking to visit the third
How have the detentions affected Crown?
* Crown's share price plunged nearly 14 per cent on Monday after the news broke and on Wednesday was at a 10-month low
* Analysts expect Crown's international "high roller" business may suffer following the detentions, an event that could affect the company's profits
* Asian business law expert Dr Alice de Jonge of Monash Business School believes the arrests will not deter companies from trying to do business in the rich Chinese gambling market.
