Meh. Kinda silly to say it was China's poison and their profit. It's also silly to think it's a huge profit for China. 450 million for them, or pretty much majority of the countries, is close to nothing.
If anything, they should be grateful they were able to buy so many respirators in the first place. Day by day it's harder to buy even 50. It's just a profit and they needed the goods. It's not like they were selling respirators for 5 million euros.
