I think US know how was needed to speed up the development. Obama's move opened up avenues for Chinese researchers to get into US labs and Universities where the brainstormers operate. No such animal outside the US.
Would mean, IMO, Obama had the pandemic planned for the 2020 election. Fauci even said, allegedly, that Trump would face a pandemic.
