The Fujian Provincial Bureau of Maritime Safety published a navigational alert on April 12, saying that the military would perform a live-fire drill in the Taiwan Straits on Wednesday. The administration released the coordinates of the drill zone-a rectangular area off the province's eastern coast-on its website, asking ships to stay out of the area.
Whether this was a reference to Wednesday's drill remains unknown.
