China launched its most extensive war games around Taiwan on Monday to showcase Beijing’s ability to cut off the island from outside support in a conflict, testing Taipei’s resolve to defend itself and its arsenal of U.S.-made weapons.
The Eastern Theatre Command said it had deployed troops, warships, fighter jets and artillery for its “Justice Mission 2025” exercises to encircle the democratically governed island, conduct live fire and simulated strikes on land and sea targets, and drills to blockade Taiwan’s main ports.
The live-firing exercises will continue on Tuesday across a record seven zones designated by China’s Maritime Safety Administration, making the drills the largest to date by total coverage and in areas closer to Taiwan than previous exercises. The military had initially said artillery firing would be confined to five zones.


You seem to be ignorant of the fact that the CPC did proclaim a new state, the People’s Republic of China, succeeding the Republic of China. In their constitution, they made territorial claims regarding what parts of the world belong to it. Just read the proclamation made by Mao where this is plainly stated.
You’re also seemingly confused regarding what “de facto” means. It does not matter what various governments recognize to be the true China, that’s more relevant for de jure. De facto speaking, the CPC has no control over Taiwan, and the KMT has no control over mainland China. They effectively govern separate states with separate territories, despite claims to the contrary (which are just claims and have no bearing on reality).
Your Canada/Quebec example falls a bit flat on its face since for it to be a proper parallel, the Quebecois declaring a new government would have to have the same role as the CPC, which is the party in China that declared a new role, not the other way around.
You’re very stuck in a dogmatic view regarding what nations/nation states/governments are, and are ignoring the messy reality of civil wars.
This is just laughable, it’s basically the first thing a military coup does, state which parts of the country it is in control of (and will soon control).
