Passengers arriving from China from Thursday (5 January) will need to show a negative Covid-19 test taken no more than two days prior to departure.
The government said the decision has been taken to introduce the measures specifically for China arrivals due to a "lack of comprehensive health information" shared by the country.
In addition, the UK Health Security Agency is launching surveillance from Sunday (8 January) which will see a sample of passengers arriving in England from mainland China tested for Covid at the point of their arrival.
