Transport Secretary Grant Shapps has confirmed that the US will be among the countries on England's coronavirus "red list", and travellers from there will continue to face 14 days' quarantine on arrival.
"I'm afraid it will be," he told BBC Radio 4's Today programme.
"The US from a very early stage banned flights from the UK.
There isn’t a reciprocal arrangement in any case there.
" The US ban on flights "hasn’t helped them to avoid this crisis", he said, as it currently has "very high numbers of infections".
Mr Shapps responded to criticism that the UK government had not properly consulted with Scotland, Wales and Northern Ireland in drawing up the list of exemptions, with the Scottish National Party accusing him of calling meetings with 38 minutes' notice.
He said the chief medical officers of all four nations were involved in drawing up the list, and that he hoped the devolved administrations would sign up before 10 July, when it comes into effect.
