If you want to get pedantic, that's de jure the case. There is only one single China recognised internationally, and it contains all of Chinese territorial claims, including the island of Taiwan. For almost all intents and purposes Taiwan is an independent country, but even they used to claim to be the one and only China until not that long ago. Unfortunately it's unlikely that a declaration of independence will be well received by China proper, so the current weird limbo (no international recognition and thus no embassies, "Chinese Taipei" in the Olympics, etc.) will persist for the foreseeable future.
