Old threats are always renewed by fresh, belligerent leaders. President (or Emperor-for-life?) Xi firmly believes in expansionism - though he rephrases this as redressal of past grievances and righting of past wrongs. He has clearly said multiple times that Taiwan is intrinsically part of China and no one can change this. He has also un-equivocally stated that the use of force will not be ruled out. The threat of China fully annexing Taiwan is a real and present danger today. It doesn't need to be done by open military invasion though. Just by consistently applying pressure over a period of time until the government and citizenry is completely dominated by the CCP. Individuals who protest are frequently 'disappeared'. When individuals can be eliminated and families suppressed and the elected government helpless to assist, the whole nation eventually kneels to the conqueror. Death by a Thousand Cuts is a valid strategy. No shots need be fired.
