Guess what Chinese officials did? They called each individual country prime minister and said: Your news reporters are criticizing China, it seems like you don't want supplies.
So politicians will talk with the boss of the news Media and explain the situation, the journalist will shut up.
This happened in two big European countries I personally know of. I suspect the same happened in the rest.
This is a beautiful reminder that you should never outsource your strategic resources like essential food, energy or medical supplies and if you do, you better don't do that from totalitarian regimes.
