The Philippines has serious human rights violations, no one protests that HK. has an extradition treaty with them.
"The Philippines’ descent into an all-out human rights crisis, with thousands of extrajudicial executions and a crackdown on basic liberties, has generated an outcry, but no strong action, from United Nations members states. The killings started soon after Duterte took office in June 2016 and continue to this day. The police insist that those killed were drug dealers and users resisting arrest, but there have been countless credible reports of the police and their agents planting guns and drugs on victims’ bodies to justify their execution-style killings.In March 2019, the United Nations High Commissioner for Human Rights said that an estimated 27,000 people had been killed, with no one brought to justice except for in one high-profile case. The police deny this figure but do admit to killing more than 6,600 people, only underscoring the need for serious investigations, which the government has unsurprisingly been unwilling to undertake."
Indonesia has an extradition treaty with Hong Kong too!
"Indonesia failed to address past human rights violations. The rights to freedom of expression, of peaceful assembly and of association continued to be arbitrarily restricted. Blasphemy provisions were used to imprison those who peacefully exercised their rights to freedom of religion and belief. At least 30 prisoners of conscience remained in detention for peacefully exercising their rights to freedom of expression or of religion and belief. The security forces carried out unlawful killings and used excessive force during protests and security operations. Two men were caned in public in Aceh after being convicted by a local Shari’a court of same-sex consensual sexual relations."
But sure, cherry pick China.
