Okay I may have worded that wrong but that is also misleading. China is a huge power (I say this is a problem as you may recall). Having diplomatic ties with China is necessary for most nations. China refuses to have diplomatic ties with anyone who recognizes Taiwan as a sovereign nation. So, everybody pretends they don’t recognize it, officially. In reality Taiwan has its own government and isn’t ruled over by China. In 1991, Taiwan/ROC even recognized the DPRC.
