With a reported 6063 new COVID-19 cases on Saturday, the government said in a statement the Kai Tak Cruise Terminal would be turned into a dedicated COVID facility with 1000 beds to mitigate overburdened public hospitals.
Hong Kong's embattled leader Carrie Lam, who attended a ground-breaking ceremony at a construction site for nearly 10,000 COVID units at Penny's Bay close to the city's Disneyland resort, said the initiatives would enhance the city's anti-epidemic capacity "within a very short period of time".
In what was seen as a rebuke to the Hong Kong authorities' handling of the spiralling outbreak, Chinese President Xi Jinping said fighting the virus must now be their "overriding mission", in comments carried in the state-backed Ta Kung Pao newspaper on Wednesday.
Hong Kong's top civil servant, John Lee, responded in a blog post on Sunday that the city's "government has entered a state of all-out combat. In accordance with President Xi Jinping's important instructions, to stabilise and control the epidemic as the overriding task."
The global financial hub's "dynamic zero-COVID" policies, mirroring those in mainland China, have contributed to its current woes and are unsustainable, some experts say.

The conversion of public housing estates, rental of commercial hotels and indoor sport centres will add an extra 20,000 extra units for people who tested positive for COVID but had no or mild symptoms for isolation.
An election to choose the city's next leader, initially scheduled for March, has been postponed to May, adding to uncertainty about the former British colony's future as Beijing imposes its rule.
