Too bad, the Vietnamese, especially its netizens, are not so friendly to China. Some even says "rather die than taking Chinese vaccines". So far as I know, the Vietnamese government rejected Chinese vaccines from the beginning and hanging around looking for Western vaccines that they finally found Astra Zeneca. Only a small amount has been imported. On the same news, it said the number of inoculation was around 170K as of today. Just for a comparison, Cambodia has inoculated its citizens up to 1.6m.
