Hong Kong’s post office has announced it would continue to suspend shipping items containing goods to the United States until further notice, despite its American counterpart having reversed its ban on packages from the city and other parts of China.

The US Postal Service says it has temporarily suspended the acceptance of international parcels from China and Hong Kong until further notice. It did not provide a reason for the suspension, but said in a statement Tuesday the flow of letters will not be affected.

The move will likely have an impact on e-commerce platforms like Shein and Temu, along with operators of drop shipping businesses.
