As with other legislation, the devil is in the detail.
> An average Chinese: Its a shame that HK as a part of China has Extradition treaties with all other countries but not Macau/Taiwan/Mainland (historical law by british).
Such simplification--Hong Kong has Extradition treaties with all other countries but not China--is not useful in understanding laws.
I would cite below a point made by Leung Kai Chi (in Chinese [1], Question 6 there), translation mine (+ Google Translate):
> 6. But some Western democracies will also sign a transfer agreement with the Chinese government?
>
> Yes, but the situation in Hong Kong is different. First, when other countries and the Chinese government sign a transfer agreement, they generally stipulate that they will not be transferring to their nationals. However, under the Hong Kong Ordinance, both residents who are born and raised in Hong Kong, or those who only transfer at the Hong Kong airport, can be detained and handed over. Second, democratic countries have election supervision. If the government misuses the handover procedure, it will be punished by the voters. The chief executive of Hong Kong is appointed by the central government. Even if the transfer procedure is misused, it is difficult to open up the responsibility. Thirdly, precisely because the Chief Executive of Hong Kong is appointed by the Central Government, the handover arrangements in Hong Kong cannot be compared with other places. Leaders of other countries can independently assess whether a suspect should be handed over to mainland China. The Chief Executive of Hong Kong is responsible to the Central Government in accordance with the Basic Law and cannot make independent decisions. Under the framework of this system, all administrative examinations under the responsibility of the Chief Executive are tantamount to a false statement.
