Li Na is targeting the No. 1 ranking and looking for more Grand Slam titles as she tries to build on her Australian Open victory earlier this year.

"I want to be number one in the world," she told reporters at Hong Kong, ahead of an exhibition match for World Tennis Day. "It's a goal, the dream for all athletes. I will try as hard as I can. There's no timing."

The 31-year-old rose to No. 2 in the rankings for the first time two weeks ago, but remains well behind Serena Williams at No. 1. Li has 6,795 ranking points, while Williams, set to move past Monica Seles and record the fifth-most weeks at No. 1, has 12,660 points.

Li does, however, lead the tour in points earned this year. She has accumulated 2,385 points, compared to Williams' 895, good for sixth place.

Despite struggling after her first Grand Slam victory at the 2011 French Open, Li feels that she can avoid a post-Slam letdown this time. Coach Carlos Rodriguez, who previously worked with Justine Henin, has also helped keep Li focused after the Australian Open.

"After I won the French Open I didn't have any experience and also nobody told me what I should do next," she said. "This time it's different. I'm working with Carlos and he has a lot of experience. He told me before what I should do."
