It is unreasonable to demand compensation from China.
What did Russia and other countries did when the pandemic started to spread? They kept their airport open, and people were freely traveling from one place to another. Not to mention that they didn't make any controls or tests to people that were coming with airplanes from China.
You are right, Russia, like many other countries, was not ready for such a situation. Putin first said that this virus is not terrible and now it does not appear in public.
As I understand it, China is being demanded to compensate for the losses caused by the untimely informing other countries about the real situation with this type of coronavirus. Too much time has elapsed between the discovery of a zero patient and informing other countries.
If this is the case then I can agree.
But all other countries around the world didn't show any other interest about the virus. They knew that it was like the SARS and MERS viruses and that there is not any antidote produced right now, and they kept being uninvolved and with no interest in China's condition.
a demand for something that causes a problem for one country because the treatment of another country can be done. but is there any evidence that can confirm this pandemic is indeed due to negligence in China? no one can be sure of that.
compensation for a country that is polluting which results in other countries being affected, of course, can be done. as long as the investigation is certain that China did it. all countries underestimate this pandemic but when they experience it, they are confused because they are unresponsive and can do so quickly to reduce so as not to dissolve.
what is needed now is cooperation between all countries so that this pandemic can be finished first compared to other things. China is needed because they can cope well and can help other countries that are not ready for this pandemic.
