The Japanese Self-Defense Force and the U.S. military reportedly named China as the hypothetical enemy in the Keen Edge exercise, according to government sources.
The ongoing exercise will continue until February 8th and consists of a computer simulation exercise that revolves around an emergency in Taiwan.
However, both countries have several multiple joint operation plans for several scenarios and emergencies, such as an invasion of Taiwan, the occupation of the Senkakus, or North Korea conducting a missile attack against Japan or U.S. military facilities in Japan.
The results of the exercise will be incorporated into the operation plan, which will be reportedly completed by the end of this year.
Both countries will conduct the Keen Sword exercise, the physical version of the exercise, in 2025 to test the operation plan.
