In its latest travel advisory update, the Foreign Ministry said that the stringent measures were imposed on “people cured of Covid-19”, as well as others who test positive for antibodies because of an undetected illness, or others who had arrived on the same flight and who test positive for the coronavirus.
“Medical measures applied by the Chinese side are invasive and include in part daily blood tests and computer scans,” the Foreign Ministry said.
All travellers arriving in China are required to serve a 14-day quarantine at a location determined by the government.
While small children are “as a rule” allowed to spend their quarantine with their parents, those aged 14 years and up can be placed in isolation away from their family.
The Süddeutsche newspaper reported that the ministry had heightened its warning after two German nationals were held in hospital quarantine for several weeks.
Both had recovered from the coronavirus previously and had tested positive for antibodies, added the report, noting that they were nevertheless forced to undergo medical tests.
The newspaper said the Foreign Ministry had filed protests with the Chinese government over how the two Germans were treated.
