The activist made the remark in the backdrop of the resolution passed by China's lawmakers to impose the Hong Kong security bill.

The bill aims at bringing the semi-autonomous territory further under Beijing's control.

Apart from criticisms by the international community, the bill had promoted severe demonstrations in the city.

The activist told Strategic News International, "Labour strike and mass mobilisation will make a come back this summer. We really wish that the world knows how we are standing to confront the largest and retiring regime in the world."

"We hope that international allies will stand with Hong Kong. Once the national security law is imposed in Hong Kong, it would just curtail its free flow of information and capital and it will no longer be the city of economic freedom," the activist said. 

Earlier, the law on Hong Kong had earned criticisms from the United States and its three major allies.

In a joint statement, the US, UK, Canada and Australia, said: "Direct imposition of national security legislation on Hong Kong by the Beijing authorities, rather than through Hong Kong’s own institutions as provided for under Article 23 of the Basic Law, would curtail the Hong Kong people’s liberties, and in doing so, dramatically erode Hong Kong’s autonomy and the system that made it so prosperous."
