That some demonstrators in Hong Kong are hell-bent on violating laws and disrupting normal life was on display again on Monday when thousands of them formed "human chains" outside schools to push for their so-called democratic demands following a weekend of violent clashes and a march urging the US president to "liberate" Hong Kong.

The fact that violence and demonstrations have continued despite the Special Administrative Region government withdrawing the bill aimed at amending the extradition law shows the protesters have been hypnotized into believing the unbelievable — that they can "liberate" the city.

What they may not have realized is that the central government under no circumstances will allow China's sovereignty over Hong Kong to be compromised.

Overt and covert foreign interference in Hong Kong's affairs has been an open secret since the protests began three months ago, with some US politicians openly throwing their weight behind the demonstrators.

Some radical demonstrators have broken every law they could break by attacking police officers and innocent passers-by, vandalizing police stations, government offices and metro stations, and paralyzing the city's international airport and harming people's livelihoods. Yet US House Speaker Nancy Pelosi and Senator Marco Rubio unabashedly call the demonstrators' terrorist-like acts a struggle for "democracy, freedom and human rights".

The United States has a long history of poking its dirty nose in other countries' internal affairs to advance its not-so-hidden agenda. It tried to do the same in the Xinjiang Uygur autonomous region, and having failed in its design there moved to the Hong Kong, where the initial protests offered it an opportunity to fulfill its political and economic goal of containing China's rise on the pretext of promoting democracy and human rights.

To further the US agenda, Pelosi said last week that US Congress members "look forward to swiftly advancing the bipartisan Hong Kong Human Rights and Democracy Act to reaffirm the US commitment to democracy, human rights and the rule of law in the face of Beijing's crackdown".

As such, the US will deliberately lend a deaf ear to the Hong Kong government, which said on Monday that "foreign legislatures should not interfere in any form in the internal affairs" of the SAR and that it was "very much in Hong Kong's own interest to maintain our autonomy to safeguard our interests and advantages under the 'one country, two systems' principle".

Hong Kong residents should be fully aware of the US plot and firmly oppose the US interference, for they will have to bear the dire consequences of their city being torn apart bit by bit by the violent demonstrators, not the dream-selling US politicians.
