whether they carry out that duty if care is another matter and there has been a lot of criticism of the embassy here.

Covid travel restrictions and emergency decree measures are not necessary the same thing, the emergency powers were invoked to deal with Covid and the democracy protesters if you choose to travel just be aware your normal travel insurance is invalid.
