U.S. researchers face new restrictions on publishing with foreign collaborators | Science | AAAS

"Grants managers at two of the U.S. government’s largest funders of scientific research have recently placed unprecedented limitations on the ability of U.S. scientists to publish with co-authors from other countries, researchers say. Units of the National Institutes of Health (NIH) are privately directing grantees to request permission in advance for any co-authorship with a scholar affiliated with a foreign institution, even if all the work was done in the United States. NASA, meanwhile, is reportedly telling some grantees that papers co-authored with researchers in China may have violated its rules."
