The Republic of China (ROC), also known as Taiwan, denies having any weapons of mass destruction. There is currently no evidence of Taiwan possessing any chemical or nuclear weapons. The development of nuclear weapons by Taiwan has been a contentious issue, as it has been cited by the PRC as a reason to attack Taiwan. The U.S., hoping to avoid escalating tensions in the Taiwan Strait, has continually opposed arming Taiwan with nuclear weapons. Accordingly, Taiwan adheres to the principles of the nuclear Non-Proliferation Treaty and has stated that it does not intend to produce nuclear weapons. Past nuclear research by the ROC makes it a ''threshold'' nuclear state.
