Why did India and the Philippines choose the South China Sea for their first joint naval exercise?

India and the Philippines share concerns about China’s growing maritime power, especially in the South China Sea, where China has expansive territorial claims. The exercise, held near the disputed Scarborough Shoal, signals both nations' intent to promote maritime security and assert a rules-based order in a region vital for global trade and regional stability.

How did China specifically respond to the joint exercises?

China sharply rebuked the drills, accusing the Philippines of co-opting other nations and claiming the exercises undermine regional peace and stability. Chinese authorities stated they are ready to defend sovereignty and that their military was conducting routine patrols in the area during the exercises.

What is the broader significance of President Marcos Jr.'s visit to India during these exercises?

President Marcos Jr.'s state visit to India aims to deepen strategic and defense cooperation, as well as expand trade, investment, and other partnerships. The timing of the visit, coinciding with the joint exercise, underscores a deliberate effort to strengthen bilateral ties and align security interests in response to China’s assertiveness.

What historical disputes exist between China, India, and the Philippines in this region?

China has a longstanding border dispute with India, including a war in 1962 and later clashes. In the South China Sea, China’s claims overlap with those of the Philippines and others, leading to repeated confrontations. These overlapping disputes contribute to ongoing tensions and shape the strategic calculations of all parties.
