China appears too aggressive and too nationalistic to think good for everyone in every country in general. They seem to think of their own citizens as numbers sometimes and expendable. So USA is worried for a good reason. So this covid timing is actually very fortuitous for humans as a whole. I guess it will encourage / force a lot of countries to be self reliant and less dependent on China.

finally, i have no idea whether India talked with usa before placing this ban. Don't know much to base my guess upon.

Totally agreed @rudra with China being very aggressive. It also has very aggressive citizens. Your point is very valid particularly today when China asked the world to stop meddling in their affairs in Hong Kong - probably referring to England's decision to allow a certain category citizens from Hong Kong to emigrate to England.

Actually India talking to USA isn't quite what I meant. I'd think that it's more a case of them always being in touch about matters like these. US has a big agenda about electronic espionage by China for decades. So I'd imagine it would keep on sending reports to India about alleged China espionage activities. The decision that was made was India's decision, with the support of the US. US didn't make it for India. But they are in touch and allies. I may be wrong of course, but this is my perception.
