Japan's actions align with other nations advocating for freedom of navigation, including the United States, France, the United Kingdom, and Germany.

Japan's chief cabinet secretary acknowledged China's expanding military presence around Taiwan and stated that Japan is closely monitoring the situation.

For the first time since establishing its Maritime Self-Defense Forces, Japan has sent the destroyer 'Sazanami' through the Taiwan Strait, marking a significant shift in its military posture.

This naval operation was ordered by Prime Minister Fumio Kishida as a countermeasure to increasing Chinese military activities in the region.

The decision to send the destroyer follows recent provocations, including the Chinese aircraft carrier 'Liaoning' crossing into Japanese territorial waters.

Japan deemed the Liaoning's passage through waters between its Yonaguni Island and Iriomote as 'completely unacceptable,' reflecting rising tensions.

In response, the Chinese government lodged a 'firm protest' against Japan's actions, asserting its vigilance regarding Japan's political intentions.

The Taiwan Strait, which is considered international waters by the U.S. and Taiwan, has seen increased naval operations from allied nations to assert this status against China's claims.

China has intensified its military deployments following the passage of warships from Japan, New Zealand, and Australia through the Taiwan Strait.

Japan's naval operation is part of joint exercises scheduled with Australia and New Zealand, emphasizing a commitment to maritime security in the region.

This naval movement coincides with discussions at the U.N. General Assembly, where U.S. President Joe Biden highlighted the importance of trilateral relations to counter China's influence.

In light of the increasing military presence from China, Japan has also reinforced its defenses on southwestern islands, which are crucial to its defense strategy.
