Pressure from the U.S. also put a halt to the Taiwanese nuclear-weapons program.
In 1976–77, the IAEA inspected the activities at the military-run Institute for Nuclear Energy Research. The IAEA discovered discrepancies in the Taiwanese program, and in 1976, the United States protested the nuclear-weapons program. In response, the island government promised to “henceforth not engage in any activities relating to reprocessing.”

Taiwan, Korea, S. Africa and Israel were all in on that development. We know that S. Africa had them before turning them over, and that Israel has them... You can guess why N. Korea never attacked the South, and why China is all bluster today.
