This is completely wrong!
First of all, the digital vaccine
certificate will be required for traveling when a country deems it necessary. No need for a global pandemic.
Second, you need to be (COVID)-vaccinated in most parts of Asia to cross a border. In many countries (and I am not only talking about China) you will still need a vaccine
certificate to travel on a local long distance bus or to just enter a shopping mall. One example for this are the Philippines. And it is not much better in other parts of Asia.
Third, if you want to board an airplane bound for Indonesia, Philippines and many other Asian nations you will need to show your COVID
certificate before boarding and it will be checked upon entry once again. Without such a
certificate you will be dried entry. Simple as that!
Just one example ->
CONSULATE GENERAL OF THE REPUBLIC OF INDONESIA in Los Angeles, United States of America
So, better read and educate yourself before posting about this matter.
