No, that's perfectly logical. Hong Kong was a remote colony that needed a governor, even after there was political reform in the UK.
Negative. Hong Kong is right next to China, it's not remote in the slightest. Guangdong is one of China's biggest cities and it's right next to Hong Kong. And China agreed to democracy when the UK agreed to hand Hong Kong island and Kowloon over to China. So there's no justification for reneging on the promise of democracy. Unless perhaps that China doesn't feel it can win the Chief Exec elections fairly.
You can only deport foreigners to another country. You can't deport your own citizens. So what - you're saying that, despite all the pro-China rhetoric, Hong Kong isn't actually a part of China?
