The East and South China Sea have become the focus of a rising security struggle in Asia. The Philippines is stepping up defense ties while China answers with diplomatic pressure and threats. These moves follow recent tensions highlighted by China’s decision to station bombers on Woody Island, a move that demonstrated its growing military reach in contested waters.
Manila strengthens alliances with “one-theatre” approach
Last week, the Philippines shared plans for a unified military strategy that will cover both the East and South China Seas. Defense Secretary Gilberto Teodoro described it as a “one-theatre” plan, which would help the country react faster and share intelligence more easily with allies. The idea came from Japan and shows that both countries now see security as a shared challenge across different seas.
This plan leaves out the Korean Peninsula but aims to connect Manila with partners such as Japan, the US, Australia, and newer allies like New Zealand and Canada. A regional coordinating center is expected to open in December to help manage these joint efforts. Japan’s support shows that it views its security closely linked with Southeast Asia, especially as tensions rise around the Senkaku Islands.
The Philippine government is also strengthening laws to protect its maritime zones. By uniting military action and legal steps, Manila hopes to push back against Beijing’s activities more effectively.
China targets former senator Tolentino with sanctions
At the same time, China has sanctioned former Philippine senator Francis Tolentino, banning him from visiting China, Hong Kong, and Macau. The decision came after Tolentino strongly supported the Philippine Maritime Zones Act and pushed for legislation that clearly defines the country’s maritime boundaries and sovereignty rights. He also repeatedly called out China’s activities in Philippine waters and backed stricter policies to assert control over disputed areas.
Instead of backing down, Tolentino described the ban as a “badge of honor” and promised to keep defending national sovereignty. Many Filipinos view his response as a bold stand against external pressure and a strong statement of patriotism.
The East and South China Sea as a shared battleground
The East and South China Sea have turned into a true battleground, not just a line on a map. Manila’s new strategy shows it does not want to face these challenges alone. Japan’s involvement proves that what happens in the South affects the East, and vice versa.
In the coming months, people will watch how the new regional center in Manila develops and whether more countries join the effort. Many expect China to answer with more naval patrols, economic moves, or more diplomatic punishments.
