Unilateral actions by China have continued in the latter half of this month.

On August 25, Japan’s Ministry of Foreign Affairs lodged a protest with China, confirming that China had taken unilateral steps to construct new structures in the East China Sea, despite the 2008 Japan-China agreement on resource development in the area.

China's unilateral actions have drawn condemnation. On August 18 and 20, the German Foreign Minister expressed concern that China is becoming increasingly aggressive in the Asia-Pacific region. He stated that China's assertive stance in the South China Sea and its behavior escalating tensions in the Taiwan Strait are threatening international security and European interests.

In terms of maritime security, on August 26, it was revealed that the Japan Coast Guard plans to deploy four additional UAVs by fiscal year 2028.This is also seen as an effort to strengthen surveillance against Chinese Coast Guard vessels repeatedly entering Japan's territorial waters near the Senkaku Islands.
