Liu Yongqing, the wife of President Hu, didn't appear official during Lien Chan and his wife's visit to Beijing, though she just came back together with Hu in the visit to Southeastern Asia the last day. As "the first lady" in China, she is supposed to meet the high officials such as presidents in other countries in case the visitor's wife comes togother with his husband. But not this time. Instead, Wu Yi, the only woman vice premier in mainland China, greeted Lien's wife and the other women visitors from Taiwan. To say is precisely, it is my speculation that Liu's disapperance shows Hu's caution in dealing with Lien's visit, though the official media highly praised the visit as a historial incidence.
I talked with a mainland friend who visited Hong Kong these says about KMT's Lien's visit to mainland China.
-"Why President Hu treated Lien at a level as high as the one other presidents enjoyed in other countries, though Lien'a party didn't have real power now?" Friend asked
Amy didn't have a precise answer. It might because CCP has to respect KMT's once domination in China. But if one day, Chen Shui-bian came to visit mainland, how CCP deal with him? higher level than Lien Chan or lower, or even equal?
But I strongly believe first lady liu will appear at that time to greet President Chen's wife.
