The HK legislature and executive aren't democratically elected, but directly or indirectly chosen by Beijing. Moreover, Beijing's control over the legislature was increased when they "reinterpreted" the agreement and removed several pro-democratic legislators a few years ago.

Beijing wants this law passed, Beijing controls the political future of those who with the power to pass the bill. The HK citizenry oppose the bill.

China is the one pushing the law. Influencing and eroding the HK political system to make it so they have more say over what HK people can say and do.

They've been slowly taking freedoms away from HK since the Xi Jinping got into office and declared himself President for life.
