Spain has become the second European country to announce new COVID restrictions for travellers from China following a surge in cases.
To enter Spain, passengers will need to have a negative test result or be fully vaccinated.
It comes after Italy earlier this week said it had ordered COVID antigen swabs and virus sequencing for all travellers coming from China.
COVID infections have risen sharply across China in December after Beijing scrapped its zero-COVID policies including regular PCR testing on its population.
China said this week that it would end mandatory quarantine on arrival, prompting many Chinese people to make plans to travel overseas.
The European Union’s health agency said on Thursday it believed the introduction of mandatory COVID screenings of travellers from China was “unjustified”.
Outside the EU, countries bringing in new curbs such as mandatory testing include the US, Japan, India, Taiwan and South Korea.
But such measures are not necessary for the EU as a whole, said the European Centre for Disease Prevention and Control (ECDC) in a statement.
On Friday, Malaysia announced it will screen body temperatures of all inbound travellers, including those from China, and those detected with fever or other symptoms will be tested for COVID.
It will also sample wastewater from aircraft arriving from China for coronavirus and will conduct tests to detect the entry of any new variants.
