In connection with the incident, Japanese Deputy Foreign Minister Takeo Mori held a phone conversation with the Chinese ambassador to Japan, during which he demanded an immediate halt to military exercises.
Earlier in the day, China launched a large-scale military exercise in the eastern Taiwan Strait in response to US House Speaker Nancy Pelosi's trip to the island.
Beijing reacted strongly to the visit, calling it a provocation and pledging that there would be serious consequences for Washington.

Beijing considers the island part of Chinese territory and sees any attempts from foreign states to establish separate contacts with Taipei as a brazen violation of national sovereignty.
