Investigations of high-ranking military officers in China primarily reflect which key policy of the central government?

💡 Explanation:

High-level investigations into officers of the People's Liberation Army (PLA) for "serious violations of discipline and the law" are generally understood to be part of the central government's prolonged and extensive anti-corruption campaign. This campaign is a primary mechanism for the Communist Party of China (CPC) to maintain absolute political control over the military and ensure the loyalty of its leadership.
