The move comes as a result of growing concerns regarding the virus in China, as well as recently implemented travel restrictions by countries including the UK and US.

Between 5-31 January, guests who have visited mainland China, Hong Kong, or Macau within 10 days prior to embarkation will be required to submit proof of a negative medically supervised PCR test taken within 48 hours prior to the beginning of travel to the port.

This also applies to guests transiting through an airport in one of the countries within 10 days prior to embarkation.

Additionally, guests will be required to take a medically supervised PCR test at the port within eight hours of embarkation, and will be required to test onboard the ship every 48 hours until 10 days have passed from their last time in China, Hong Kong, or Macau.

Passengers must also be fully vaccinated and boosted with a World Health Organization approved vaccine prior to embarkation.

It comes after the EU recommended all passengers travelling from China to the EU should be required to provide evidence of a recent negative test for Covid-19.

China’s foreign ministry spokesperson this week said the restrictions being imposed on travellers from China "lacked scientific basis", adding the Chinese government would now consider reciprocal countermeasures.
