By this spring, all national universities in the nation had created export control sections to prevent nuclear, radar and other high-level technologies with the potential for military use from being transferred abroad, and had set relevant rules, according to the education ministry.

Last year, five of the 86 state-run universities did not have such units and 17 had lacked rules on export controls. But as of April, all of the institutions had introduced both, a tally by the Education, Culture, Sports, Science and Technology Ministry showed.

Universities in Japan have faced growing calls to tighten their export controls and the United States, which has raised questions about China stealing technology, has called on its allies to take such steps.
