You're welcome. It's often called the 'one airline one route' policy by China. It also explains why many Chinese carriers will launch as many routes as possible to squat on them, even if they are immediately unprofitable.
Such as Los Angeles to Changsha, Vancouver to Zhengzhou, Seattle to Shenzhen. This is independent of government-influenced routes such as Beijing-Montreal-Havana.
