HONG KONG (REUTERS) - Hong Kong authorities said on Sunday (Feb 13) that supplies of vegetables and chilled poultry into the global financial hub may be temporarily disrupted after some mainland goods vehicle drivers preliminarily tested positive for Covid-19.

Hong Kong imports 90 per cent of its food, with the mainland its most important source, especially for fresh food.

Consumers have already seen a shortage of some foreign imported goods, including premium seafood, due to stringent flight restrictions.

"The mainland authorities and the (Hong Kong) government are working closely together to firm up the detailed arrangements to expedite the logistics of food supply for Hong Kong so as to make the supply situation resume normally as soon as possible," the government said in a statement.

On Saturday, the city of 7.5 million people reported a record 1,514 new coronavirus infections, up from last Friday's 1,325, in the biggest test yet for the Chinese territory's "dynamic zero-Covid-19" strategy.

After a meeting with mainland Chinese officials across the border in Shenzhen, Hong Kong's No. 2 official, Mr John Lee, said on Saturday that China will help the city to cope with the expanding outbreak by providing testing, treatment and quarantine capacity.

He said there were no plans for a mainland-style lockdown for now.

The measures will give Hong Kong breathing space as medical capacity becomes stretched on all fronts, although there were no specific details of the plans and it was not clear how quickly they could be implemented.

Hong Kong and mainland China are among few places in the world still aiming to suppress every Covid-19 outbreak, but the Omicron variant has proven tough to keep under control.
