LONDON, Nov. 10  -- With the help of "revenge spending" from the COVID-19 pandemic, sales of Wednesday's "China's Singles' Day" online shopping festival, which is similar to "Black Friday" in Western countries, is expected to break new records, the BBC reported Tuesday.

Noting that "China's Singles' Day", which falls on Nov. 11 annually, is the world's biggest 24-hour online shopping event, with 1.9 billion products ordered and delivered last year, the BBC said it is thought that pent-up demand from the pandemic will help to break new sale records.

Robot cleaners, vacuums and toolboxes are all expected to be popular items for shopping carts. And luxury brands are also hoping to get a boost, as millions of Chinese have been unable to travel overseas because of the pandemic, said the BBC.

"We anticipate ongoing international restrictions will cause a meaningful shift in Chinese consumers buying luxury online," Michael Norris at the market research firm AgencyChina told the BBC.

"Luxury brands have also risen to the occasion, with an estimated doubling in the number of luxury brands participating in Singles' Day," Norris was quoted as saying.
