Experts on Thursday slammed the recent move of a group of "Hong Kong independence" advocates after they registered a political party in the UK to channel overseas funds to support independence movements in Hong Kong.

The "Hong Kong Independence Party" was formed at the end of February in the UK by a protégé of Hong Kong scholar Chin Wan, who advocates "Hong Kong independence," reported Hong Kong-based Zijing magazine.

Chin is an academic and the author of a widely discussed book that advocates Hong Kong becoming an independent city-state. He has been spreading information about "Hong Kong independence" online.

The magazine said the party follows the practice of separatists in the Tibet Autonomous Region by setting up an organization overseas to receive donations and funding to finance the local independence movement.

The magazine also alleged that the party had been accepted by the election committee in the UK on February 27, and is now a legitimate party in the country.

Zijing reported that Chin cooperated with Hong Kong-based political group Civic Passion, which has become the most active group in the city's political scene following the end of Occupy Central, a mass protest calling for "genuine democracy" in the ongoing political reform.

It is against the Basic Law to form a separatist organization. It can jeopardize State security if such an organization becomes active and transfers funds to China, according to Mo Jihong, a research fellow at the Chinese Academy of Social Sciences.

Mo added that Hong Kong authorities are obliged to take measures and strengthen its supervision while both Hong Kong and the Chinese mainland should set up or improve relevant laws and regulations,

Yin Hongbiao, a professor of international relations at Peking University, told the Global Times that China is facing threats from "Hong Kong independence" activists who try to damage relations between Hong Kong and the Chinese mainland.

"Hong Kong society not only needs democracy, but also needs to develop people's welfare. It is wrong to only choose one aspect," Yin said.

In March, Zhang Dejiang, chairman of the National People's Congress, warned that calls for independence were "intolerable" and would seriously jeopardize overall national interests.
