Hundreds of protesters took to their anti- Beijing message to the UK’s Consulate- General in Hong Kong on Sunday as they called on the UK to take actions against China for allegedly failing to keep its so-called “one country, two systems” promise.

The rally, organized by a pro-democracy online group, sought to urge the UK government to “take immediate action on China for not honouring the Sino-British Joint Declaration” and “acknowledge” that the formula established in the handover deal reached between the two powers in 1997 was “not functioning”.

Under the “one country, two systems” formula, Beijing agreed to allow the former British colony to retain a semi-independent status – including certain legal rights not contained in the mainland Chinese system – until the pact’s expiration in 2047.

Sunday’s crowd waved US flags and chanted pleas for the US to “liberate” Hong Kong from China.

One of the participants in the rally, a man said the formula was “virtually dead”.

“I hope the UK will make China adhere to the Sino-British Joint Declaration so that we can have universal suffrage, as we have been promised”, he added.

One masked organizer said that the Sino-British Joint Declaration was being breached and that the “one country, two systems” formula was dysfunctional while reading a statement to the crowd.

He also claimed that “each and every aspect” of Hong Kong was under the direct command of the Chinese government.

The rally came exactly one week after 250,000 people marched to the consulate general of the US, calling on Washington to pass a congressional bill that could restrain the Hong Kong and Chinese governments from suppressing the city’s human rights and freedom.

Last week, Hong Kong leader Carrie Lam warned the United States not to “interfere” with her government’s response to the city’s pro-democracy movement after fresh protests called on Washington to ramp up pressure on Beijing.

Earlier in the month, Lam now has formally withdrawn the proposed law. The move meets one of five demands made by the protestors.

Other demands include an independent investigation of reports that some police officers brutally attacked demonstrators. Another is for Hong Kongers to have more freedom when choosing their own leaders.
