China under-representing Covid deaths, WHO warns
Wednesday's recommendation on negative tests came from the EU's Integrated Political Crisis Response group (IPCR), a body made up of officials from the EU's 27 governments.
It also advised that:
All passengers on flights to and from China wear face masks
Random testing of flights from China be introduced, and
Wastewater monitoring be conducted at airports.
The recommendation comes a day after the European Commission, the executive body of the European Union, said an "overwhelming" number of member states favoured restrictions on Chinese arrivals.
