Well i agree both with some Chinese members and bussard on here . The CCP is indeed the ruling party in china, so the army /military ought to listen to /follow the ruling party /government /presidents orders like it does in the West and everywhere else. So nothing different /special about that. in this regard, i agree with Chinese members here.
However. Bussard is correct when he says corruption /nepotism and favoritism in the military and party can indeed be a big threat to the party survival /control over the Army /country. If the party doesn't evolve /reforms then it too will be consumed by these 3 great ills i mentioned and topple as well just like the party toppled it's predecessor KMT before it rose to power. So I agree with bussard that as Lee Kwan yu said : "Either you make fundamental changes, and change power by consensus, or there will be a revolution with violence." that's indeed a very important statement which the CCP has to bare in mind.
Also the main problem with the CCP just like with any other communist one party state (like Vietnam. North Korea or Cambodia) is that the Party comes before the country /state and the party is above both the constitution and everything else. In short, the Party is the state. reason corruption often gets spirals out of the party control since there are no independent/authoritative checks and balances who can surpervise the party itself. Any public criticism against the party (especially by public individuals, high ranking official, citizen) is seen as an attack against the country itself, not just the party. That's a very wrong system, which means even n ultra patriotic Chinese or Vietnamese citizen who loves his country but despise the ruling party will be considered a traitor /liberal outcast etc and treated accordingly /discarded. Anybody can love his country but still despise the party, that shouldn't be considered an offence at all. So i think the CCP just like any other one party communist state ought to reform in some aspects, else at 1 point when the positives they have contributed falls short of the negatives they too might be toppled as they did with the former ruling party.
what goes around comes around.
adapt and change else change will come to you by force.
In conclusion, I will say the biggest difference between the communist one party system and other multi party democracies is that, the military is so politicised in one party regimes that it owes it's allegiance/serves tje party first before even the country. For example, if the party was in danger of losing power. The CCP /VCP etc can call in the army for help (like they did during the Tienanmen square massacre) to maintain power irregardless of the consequences to the country , while in a multi party democracy, there's no way/guatanter will listen to the parties call since it had little to no business in politics. So yes communist one party regimes have more political control /loyalty over the Army.
