Most of the reponses I see are racist in nature to what China will or will not do. Everyone greatly under estimates the great intellegence that Chinese have. There history stretches back thousands of years and they are keenly aware of what is right and wrong. Recently as an example the Nanjing massacare that took place during WWII that is denied by Japan and so on and so on. Chinese will think first very carefully they have a great love and respect for our Jewish Nation. G-d bless them to make it known to the world of this love for the Jewish people and Israel. Chinese are never in denial they leave that to the Japanese. They know what fascism is and iran is the center of it. They will not cover up there intentions and fake some stupid story. They are examining what is in there hands to be sure to make there decision independent of political or economic considerations, just what is right and wrong and what could lead to something like what happened in Nanjing or worse G-d forbid.
