The bill would toughen disclosure requirements for research organisations that get funding contracts from any country, including close US allies. Under the law, the threshold for reporting most foreign funding would fall to $50,000 a year from the current $250,000 – and unlike at present, the reports would be publicly available. For “countries of concern” – such as China and Iran – the threshold would drop to zero.
