Livni did not go to china expecting an immediate change in China's position. She went there to tell the Chinese that Israel's concern is independent of the USA's policy and to explain them where Israel's concerns come from. She wanted to be sure that the Chinese understand their point of view so as not to claim in the future: why did u not tell us. I doubt if Livni expected results immediately. How her trip might affect Chinese actions in the future remains to be seen. I would not assume that her trip will have no rewards.
