British parents travelling in China could be separated from their children should one person test positive for coronavirus.
Every country on Earth has introduced new travel restrictions and laws since the onset of the pandemic earlier this year.
But mainland China is the only country whose UK Government foreign travel advice page warns has a policy of family separations in the event of a positive Covid-19 test.
"The Chinese authorities continue to impose various control and quarantine measures across the country, including restrictions on movement, reduced transport, entry and exit controls for towns and villages, and isolation requirements for travel between different parts of the country," the official website reads.
"You may be separated from your child if one of you tests positive for coronavirus. If this happens to you, you can call +86 (0)10 8529 6600 for 24/7 urgent consular assistance.
"Non-residents may be charged for their care."
The information is a new addition to the Foreign Office's official travel advice, having been added to the page on Friday.
It is unknown how long families might be separated if one member tests positive.
It is also unclear if very young children are exempt from the policy and where they will be housed if the policy leaves them alone with no parent or guardian.
The harrowing policy is the latest deterrent against travelling to other countries while coronavirus still runs rampant with little hope of a vaccine until next year.
The UK Government still advises British nationals against "all but essential international travel" as the world fights to get the pandemic under control.
Anyone wishing to enter China will need to submit a Health Declaration Form beforehand, and must provide evidence of a negative Covid-19 test (taken privately) no more than three days before travel.
Brits returning to the UK from a trip to China will need to self-isolate for 14 days upon their arrival.
China, the original epicentre of the coronavirus pandemic, claims to have just 265 active cases of the disease.
However the country's reported statistics have been questioned by world authorities, with some accusing the Chinese Communist Party of covering up the real number of cases and deaths.
The official death toll in China currently stands at 4,634, but various Chinese scientists have claimed fatalities may have been concealed.
