No point of view in article titles is not a guideline.  In all cases, it is neutrality, and the NPOV POLICY, and the Naming conflict guideline that the policy summarizes all make it very clear that the existence of the ROC is not a consideration to deny that the most common usage of China is to mean the country we call People's Republic of China.
Wikipedia:NPOV#Article_naming Where proper nouns such as names are concerned, disputes may arise over whether a particular name should be used. Wikipedia takes a descriptive rather than prescriptive approach in such cases, describing corporate entities such as cities and states by the names by which they describe themselves (or by the English-language equivalent). Where inanimate entities such as geographical features are concerned, the most common name used in English-language publications is generally used. See Wikipedia:Naming conflict for further guidance.
The followup guideline, Naming conflicts, entirely disagrees with you.  The common name (in use by the world), the self-descriptive name (of the PRC), the official short name (ie, the UN) of the PRC is simply, ""China"".  The guideline says that subjective criteria such as someone else's claim to the term China (ie, the ROC), should NOT be used as criteria to determine Wikipedia's usage.  "
