Mercedes-Benz and China Open began their cooperative efforts in August 2004. From the very beginning of China Open four years ago to its current status as one of the world's most prestigious tennis events, Mercedes-Benz, its most important sponsor, has continued to strengthen its commitment to China Open, enabling a sustainable development of the competition with every successive year.

Mercedes-Benz has long been an important sponsor of China's tennis events. At the end of 2002, with Mercedes-Benz as the chief sponsor, Tennis Masters Cup, the world's highest-ranking professional tennis tournament, came to China and became the highest-level tennis contest hosted by China. At the 2006 Tennis Masters Cup, Mercedes-Benz provided its brand-new R 350 Grand Sports Tourer and S 350 L sedan as official vehicles for the game. Notably, Mercedes-Benz also offered a brand-new R 500 as an award for the champion of the Tennis Masters Cup.
