Your upper map is labeled Republic of China, not People's Republic of China, and ROC and PRC are referred to as separate entities in various places, strongly implying that this is the ROC government's (i.e. Taipei's) irredentist view of what THEY should control. The giveaways are the labeling of Taipei as the 'provisional capital' and the note that the islands to the north (Ryukyus? Can't tell) are claimed by both the ROC and the PRC.
This map is 'Made in Taiwan', figuratively if not literally.
