Those in Vietnam for temporary business trips should complete self-quarantine for at least 14 days before boarding. All applicants are required to upload the Letter of Commitment on Self-quarantine stamped by enterprises/companies.

5. Applicants having received all required doses of Covid-19 vaccines for more than 14 days are regarded as vaccinated. Those who only get 1 out of 2 doses or get 2 doses on the same day are NOT regarded as vaccinated. Applicants vaccinated are required to board the plane 14 days after the last dose of vaccine. Application for the health code will not be approved if the date of receiving the last dose is less than 14 days away from boarding, even if the nucleic acid and IgM anti-body tests results are negative.

If the IgM anti-body test result is positive, please upload the certificate of Covid-19 vaccination.

6. Applicants infected with Covid-19 before refer to cases confirmed at a medical institution; those whose nucleic acid test, IgM (not caused by vaccination) or IgG anti-body test is positive (either one testing positive will count). These applicants are required to provide a diagnosis certificate of pulmonary CT/X-ray scan issued by a local hospital and nucleic acid test results with samples collected 2 times with an interval of at least 24 hours. Tests results should be sent to the email boxes of Chinese embassy/consulates within 3 days after the second nucleic acid test. Upon reply from the Chinese embassy/consulates, one needs self-quarantine for 14 days before applying for the green health code.

7. Embassy/Consulates of China in Vietnam will not issue health code for passengers transiting via a third country, Hongkong SAR, Macao SAR or the Taiwan province of China. Please choose direct flight to China. Consequences like getting repatriated or stranded at the airport, and economic losses caused by transit will bear on the individual.

Ⅴ. For passengers transiting via Vietnam

Strict visa and entry policies are implemented now in Vietnam, foreigners without valid visa cannot enter Vietnam. In addition, airports in Vietnam do not provide nucleic acid and IgM anti-body tests. Passengers transiting via Vietnam will face high risk of getting stranded. Therefore passengers departing from a third country are advised not to transit via Vietnam.

Ⅵ. Procedure of applying for the green health code

All Chinese and foreign passengers need to upload photos of their valid identity, residence permit and negative nucleic acid and IgM anti-body tests results to the WeChat Health Code app (Attachment 2) or via website Then they will get the green health code with the "HS" or "HDC" mark after approval from the Chinese embassy/consulates. Passengers must present the green code within its validity to the airlines flying directly to China before boarding.
