Li Na has secured her place in the WTA Championships final after beating Petra Kvitova in straight sets.
The world number five came through 6-4 6-2 to book her place in the final.
Li started the match in fine form, breaking her opponent in the opening game before showing her prowess at the net to hold serve.
She broke again to make it 3-0 but Kvitova came back with some powerful ground strokes and made it 3-2. The two women exchanged breaks again at the end of the set before Li held to take the opener 6-4.
The second set was a shorter one as early breaks for the Chinese player broke Kvitova's spirit and Li wrapped up the match comfortably.
