Covid-19 travel restriction's

China Covid: Beijing criticises 'political' rules for its tourists

The US, India and the UK are among the nations that have introduced mandatory testing for arrivals from China.

BBC report the country has recently seen a surge in Covid cases following the easing of its strict controls.

And there are fears that cases and deaths are being vastly underreported.

China's last daily Covid update, on 24 December, reported fewer than 5,000 cases - but some analysts claim the daily caseload is already over two million, and could peak at almost four million this month.
