"Intensifying repression by Beijing has reached such a level that Apple Daily, a much-needed bastion of independent journalism in Hong Kong, has now ceased publishing.

"Through arrests, threats, and forcing through a National Security Law that penalizes free speech, Beijing has insisted on wielding its power to suppress independent media and silence dissenting views," Joe Biden said in a statement as posted by the White House.

"Independent media play an invaluable role in resilient and prosperous societies. Journalists are truth-tellers who hold leaders accountable and keep information flowing freely—and that is needed now more than ever in Hong Kong, and in places around the world where democracy is under threat. Beijing must stop targeting the independent press and release the journalists and media executives that have been detained. The act of journalism is not a crime," he said.

He said people in Hong Kong have the right to freedom of the press. 

Criticising Beijing, Biden said, "Instead, Beijing is denying basic liberties and assaulting Hong Kong’s autonomy and democratic institutions and processes, inconsistent with its international obligations. The United States will not waver in our support of people in Hong Kong and all those who stand up for the basic freedoms all people deserve."

Some 500 policemen raided the offices of pro-democracy paper Apple Daily in Hong Kong recently by alleging that the report published by it breached a national security law.

Police also arrested the editor-in-chief and four other executives at their homes. It also froze HK$18m ($2.3m; £1.64m) of assets owned by three companies linked to Apple Daily, reports BBC.

Jimmy Lai is the owner of the paper. He is currently in jail and facing several charges.

Apple Daily is known to be critical of the mainland Chinese leadership, reports BBC.
