alistair What’s ‘newspaper bollocks’?
Well, the UK could make it difficult for Chinese travellers, simply to reciprocate the difficulties China’s closed borders and quarantine have caused UK business travellers to China. I actually think that level of petty spite is actually what’s pushing Japan and the US’ policies rather than genuine concern about a new variant that ‘might’ emerge. It is of course reasonable - this is how international diplomacy is sometimes conducted.
As Grant says it probably wouldn’t actually stop whichever variant arriving though.
