As much as I have suspicions, I really don't think that was involved. Maybe I am just to naive.Money laundering. How many of those taxpayer dollars came back as campaign donations or other favors to the politician(s) that sent the money to China?
However, NIH grants always are divided into direct and indirect (administrative ) costs. Indirect costs are not a trivial part. If one considers that the maximum R01 grant is $250,000 per year for 5 years for direct costs, and if only one such grant was given, that leaves a minimum of 3.7 - 1.25 = $2.45 million to the Chinese Communist Party. NB: There may be two R01 grants involved. The only one I tracked was R01AI 110964 which is acknowledged in this paper: https://www.nature.com/articles/s41586-018-0010-9
