It's sad to see a situation like this in the scientific community. The larger part of international chinese researchers are probably worried if this is spreading to non-US countries. Most of researchers I know returned to China in these programmes simply wanted a secure/easier/family life, which probably means they won't be outputting much research as the new environment won't be as creative and competitive as in the U.S /European research fields. I'm shocked to find these alleged espionage cases which seem to paint the opposite picture.
