headline: Covid in China: Checks on visitors under review - UK defence minister
text: UK government is reviewing whether to introduce Covid restrictions on visitors from China, the defence secretary has said.
  Ben Wallace said the Department for Transport would take medical advice and talk to the Department of Health.
  Earlier, an ex-health minister urged the government to consider testing arrivals from China for Covid.
  A number of countries are introducing mandatory testing in response to China's coronavirus surge. 
  Asked whether the government would consider restrictions, Mr Wallace said: "The government is looking at that, it's under review, we noticed obviously what the US has done and India and I think Italy has looked at it."
  "We keep under review all the time, obviously, health threats to the UK, wherever they may be."
  Several countries - including the US, Japan, Italy and Malaysia - are now enforcing testing on visitors from China. 
  follows a surge in cases in China after Beijing's decision to effectively end its zero-Covid policy.
  UK Health Minister Will Quince said he knew that many people would be concerned "about the news coming out of China" and the government was taking the situation "incredibly seriously".
  However, there was "no evidence at this point of a new variant from China", which he said would be the "key threat".
  "At the moment the variant that is in China currently is already prevalent here in the UK."
  Meanwhile, the Scottish government said it currently has no plans to change travel requirements, and would continue to work with the UK Health Security Agency and other countries to "monitor the spread of harmful variants".
  In 2019, 813,532 visas were issued to people wanting to travel to the UK from China. This dropped to less than 200,000 over the following two years, owing to Beijing's strict Covid border controls. 
  re are concerns that a new variant may emerge in China and that international travel could quickly spread it. 
  When there is lots of virus circulating in any population, there will be opportunities for it to change or mutate in potentially harmful ways.
  Covid is circulating in lots of countries around the world. 
  According to latest estimates for the UK, one in every 45 people in Britain is infected. 
  Vaccines are saving lives but they can't stop infections. Instead, experts are tracking the virus and seeing if the vaccines need updating to be a better match for any significant new mutations. 
  So far, science is keeping up with the virus and there are no particularly worrying new variants. 
  Lord Bethell, who was health minister during the pandemic, told the BBC there was a good reason to look at testing people when they land, a policy Italy has adopted.    
  "What the Italians are doing is post-flight surveillance of arrivals in Italy, in order to understand whether there are any emerging variants and to understand the impact of the virus on the Italian health system," he told BBC Radio 4's Today programme.
  "That is a sensible thing to do and something the British government should be seriously looking at."
  China is reporting about 5,000 cases a day, but analysts say such numbers are vastly undercounted - and the daily caseload may be closer to one million.
  Prof Paul Hunter, professor in medicine at the University of East Anglia, said he did not think the current situation in China was likely to generate many more Covid cases in the UK or generally across the globe.
  While China was in a "dark" and "difficult" place, the current evidence suggested the particular variant causing most infections in the country was "very common elsewhere in the world", he told BBC Radio 4's PM programme on Wednesday. The UK has seen many such cases since it appeared in the summer, he added.
  On Wednesday, the US said a lack of "adequate and transparent" Covid data in China had contributed to the decision to require Covid tests from 5 January for travellers entering the country from China, Hong Kong and Macau.
  Others have also announced restrictions:
  On Thursday, Italy urged the rest of the EU to follow its lead and ensure Chinese arrivals were tested. However, the EU's disease agency said the surge in cases in China was not expected to impact members states and said screening travellers from China for Covid would be "unjustified".
  Beijing's foreign ministry has said coronavirus rules should only be put in place on a "scientific" basis and accused Western countries and media of "hyping up" the situation.
  China only announced on Monday its decision to end quarantine for arrivals - effectively reopening travel in and out of the country for the first time since March 2020.
