HONG KONG >> Hong Kong’s leader signaled Monday that her government will go ahead with proposed amendments to its extradition laws despite a massive protest against them that underscored fears about China’s broadening footprint in the semi-autonomous territory.

Chief Executive Carrie Lam told reporters the legislation is important and will help Hong Kong uphold justice and fulfill its international obligations. Safeguards added in May will ensure that the legislation protects human rights, she said.

In what appeared to be Hong Kong’s largest protest in more than a decade, hundreds of thousands of people marched through central Hong Kong on Sunday, three days before the Legislative Council is slated to take up the bill.

Hong Kong was guaranteed the right to retain its own social, legal and political systems for 50 years under an agreement reached before its 1997 return to China from British rule. But China’s ruling Communist Party has been seen as increasingly reneging on that agreement by pushing through unpopular legal changes.

The extradition bill amendments would allow Hong Kong to send people to mainland China to face charges, spurring criticism that defendants in the Chinese judicial system won’t have the same rights as they would in Hong Kong. Opponents contend the proposed legislation could make Hong Kong residents vulnerable to vague national security charges and unfair trials.

Lam said Sunday’s protest shows Hong Kong’s enduring commitment to its people’s freedoms. She denied that she is taking orders from the central government in China’s capital.

“I have not received any instruction or mandate from Beijing to do this bill,” she said. “We were doing it — and we are still doing it — out of our clear conscience, and our commitment to Hong Kong.”

Hong Kong currently limits extraditions to jurisdictions with which it has existing agreements or to others on an individual basis under a law passed before 1997. China was excluded because of concerns over its poor record on legal independence and human rights.

Lam was elected in 2017 by a committee of mostly pro-Beijing Hong Kong elites. Critics have accused her of ignoring widespread opposition to the extradition law amendments.

She said Monday that the bill seeks to prevent Hong Kong from becoming a haven for fugitives and is not focused on mainland China. Western democracies have accused Hong Kong of failing to address issues such as money laundering and terrorist financing, Lam said.

Sunday’s demonstration was mostly peaceful, though there were some late-night clashes between some remaining protesters and police. Three officers and one journalist were injured, according to Hong Kong media reports.
