I recently heard something on the financial predicament the US dollar is in, which explains some of the tension with China in particular. On the one hand if they don't raise interest rates then no-one will want to hold the dollar, so China is looking to offload it's dollars which will cause financial collapse for the US (and the western world in general). However, if they raise interest rates this will also cause financial collapse as people and countries start to forfeit on debt payments. Something of a catch 22 situation it seems.
War is often the way politicians try to get out of sticky situations and rally the people to find another country or culture to blame. This blaming of China for the virus feels a little like the blaming of Jews for the miserable financial situation back in the 30s.
