Tickets for the 2013 China Open tennis tournament went on sale on Tuesday, as the highest-level tennis event in China will celebrate its 10th anniversary in the capital city.

Organizers said more price categories are available for spectators to choose from this year. Customers can buy tickets through the official website, agencies' websites or the booking hotline. Those who buy tickets before August can get better prices.

This year's China Open will run from Sept 22 to Oct 6.

In addition to local favorites Li Na and newly crowned Grand Slam women's doubles co-winner Peng Shuai, the event will have the No 1-ranked male player, Novak Djokovic, and Spanish ace Rafael Nadal, all of whom have confirmed their participation.
