However, such virus already exists in the wild, though the chances are there, it can jump to human anytime in the future regardless of national boundaries.
I've experienced living in a small, developing nation for years, and while they have the same dangerous mixture as China of live animals (and the associated excretions), dead animals, produce (unwashed, washed, and already skinned for consumption all available from the same table), fertilizer of human origins, farming supplies, pesticides, medical products, hygiene products, clothing, food transport, food storage, food preparation surfaces, cutlery, dish ware and dining surfaces all overlapping to alarming degrees (often sharing the same surfaces at different times), they don't have the potential global role, both based on their size, relative lack of population, lack of foreign travel and foreign entanglements, and so on.
Inadvertent power projection from a biological perspective is an interesting concept.
Edit to add: I can't judge the people working in these markets and offering products under horrendous conditions. They're trying to feed their families. But China needs to get serious about public health if it hopes to improve its reputation, which is roughly the same from Tehran to Toledo with some justification.
This particular pandemic was entirely avoidable in the first place. Food markets in developing nations frequently cause local health problems, and have all the ingredients to make a global one (as it seems to have in this case).
COVID-19 may be from China, but a pandemic can come from anywhere and will come again. You can taking chance on its virality/mortality.
