@KYli and
@Hendrik_2000 there's no forever friend nor forever enemy.
Let the past be gone and move forward. If China doesn't donate vaccines to Vietnam now, the US will do it and they are doing it.
Vietnam is currently in really deep water with daily cases going up every day likely 4,795 new cases today and not peak yet. Vietnam has 98 million people and if 70% of them need to be vaccinated, it would be around 69 million people or 138 million doses. That's a lot for them. So they are trying to use their geopolitical advantage to gain free vaccines. China has donated a lot of vaccines worldwide, why not include Vietnam? If you don't donate vaccine to me (VN), I will go to uncle Sam to get it and don't blame me for not warning you in advance (Sic)!!!
