The company has sponsored Li Na since September 2011, the same year the Chinese star won her first grand slam tournament, the French Open.
Crown executive chairman James Packer said the deal was a way of strengthening the company’s brand in Asia and was its most important sports sponsorship.
“The Henry report into the Asian century commissioned by previous prime minister Gillard actually showcased Crown as being one of the best Australian companies in terms of engaging with Asia already,” Mr Packer said in Beijing on Monday.
“But for us to have an association with the most popular athlete in the biggest country in the world is an honour, really.
“I don’t think anyone personifies the rise and success of China in a sporting sense more than Li Na.”
