"Such a decision strongly indicates that the authorities in mainland China are determined to eliminate dissenting voices and opinions in Hong Kong," the Japanese Foreign Ministry said in a statement.

The package of changes approved by the National People’s Congress, combined with mass arrests of pro-democracy activists and politicians, undermines Hong Kong’s high degree of autonomy under the “One Country, Two Systems” principle.

"The package will also stifle political pluralism, contrary to the aim of moving towards universal suffrage as set out in the Basic Law. Furthermore, the changes will reduce freedom of speech which is a right guaranteed in the Sino-British Joint Declaration," read the statement.

"The people of Hong Kong should be trusted to cast their votes in the best interests of Hong Kong. Discussion of differing views, not silencing of them, is the way to secure the stability and prosperity of Hong Kong," the statement said.

"We call on China to act in accordance with the Sino-British Joint Declaration and its other legal obligations and respect fundamental rights and freedoms in Hong Kong, as provided for in the Basic Law. We also call on China and the Hong Kong authorities to restore confidence in Hong Kong’s political institutions and end the unwarranted oppression of those who promote democratic values and the defence of rights and freedoms," the statement said.
