Chinese is not a single language but spans a large subset of the Sino-Tibetan language family. They tend to mostly differ in their phonologies and not much in syntax and vocabulary, so written logograms could enable communication otherwise impossible. The script was also adopted by, for example, Koreans so they could do the non-verbal communication in written Chinese. You probably cannot expect this kind of uniformity across the whole Indo-European languages.
