Australia, Japan, and China engage in naval exercises in response to rising tensions and concerns over territorial disputes.

The exercises, which took place in the East China Sea, involved a range of vessels, including destroyers, frigates, and submarines.

The exercises were designed to enhance maritime cooperation and interoperability between the three countries.

The exercises were held against the backdrop of rising tensions in the Asia-Pacific region. China has been increasingly assertive in its claims to territory in the East and South China Seas, which has led to concerns from other countries in the region. The United States has also been increasing its military presence in the region in order to counter China's growing influence.

The exercises were seen as a signal of the growing cooperation between Australia, Japan, and China. The three countries have been working to build closer ties in recent years, and the exercises were seen as a further step in that direction. The exercises also underscored the growing importance of the East China Sea as a strategic waterway.

The exercises were not without their critics. Some analysts argued that the exercises could be seen as provocative by China, and that they could lead to further tensions in the region. Others argued that the exercises were necessary to ensure freedom of navigation in the East China Sea and to deter China from further aggression.
