Philippine Academic Calls for Japan-Philippines-Taiwan Defense Cooperation Against China
What happened
A professor from De La Salle University, Renato Cruz De Castro, spoke at a forum in Taipei on October 20, 2026, calling for defense cooperation between Taiwan, the Philippines, and Japan. De Castro stated that China's operations in disputed waters near the Philippines in the South China Sea prompted Manila to adopt its Comprehensive Archipelagic Defense Concept (CADC). He also stressed the importance of Japan's role in defending the first island chain under Prime Minister Sanae Takaichi.
