Because the two terms are interchangeable, it’s not outside the realm of possibility for someone from China to refer to the party as the CCP, and vice versa. For example, the US state department acknowledges that CCP=CPC but uses CPC despite not being from China. Thus, someone in China may also use CCP. Since people refer to things differently, just because #4 uses a more uncommon phrase doesn’t mean they’re not Chinese.
