That was my question. Who need Vietnam to make their vaccines. I think it is just that Vietnam wants to take the chance with India and South Africa in morally forcing the developers to give things (tech or market) for free or cheap.What type of vaccines would Vietnam make? Moderna and Biontech are made in the US, Europe and by Fosun in China soon. Astrazeneca is now avoided by many countries. Are the Vietnamese going to make Sinovac and Sinopharm for China?
No, I don't think China would allow Vietnam to make any Chinese developed vaccines. The ones who received such tech export are China's regional allies who have been openly supporting China or regional heavy weights who have remained neutral and cooperative. Vietnam is neither of these.
