China is a dictatorship. Taiwan is a democracy.
Hence, the New York Times could observe a few days ago: “While Chinese commentary was resoundingly positive about Saturday’s meeting between president Xi Jinping of China and president Ma Ying-jeou of Taiwan, reactions in Taiwan was decidedly mixed.”
In a democracy, when the leader does something it gets debated. Out of debate comes wisdom. That’s a pretty strong case for democracy.
China sometimes looks unified, but it is the unity of open debate that is solid.
