The Philippines aims to finalize a code of conduct for the South China Sea during its ASEAN chairmanship in 2026. Manila wants a legally binding agreement to manage disputes in the contested waters. But this goal faces major challenges. Relations with China have worsened after confrontations at sea. China claims most of the South China Sea, clashing with the Philippines and others. Beijing says it acted with restraint near Philippine boats, while Manila claims Chinese coastguards used water cannons and cut anchor lines, injuring fishermen and damaging vessels. The 2016 Hague tribunal ruled against China's claims, but China rejects this verdict. Diplomatic experts believe disagreements over legal terms and sovereignty make a deal unlikely. Some ASEAN members seek a softer agreement focused on cooperation, while the Philippines and Vietnam push for binding terms. The Philippines also faces domestic pressure to take a tough stance. Experts say the code of conduct will highlight ASEAN talks but is not a complete solution. They call for stronger direct communication and practical cooperation on environment, research, and disaster relief. As the region watches, Manila's push may be more symbolic than a true breakthrough amid complex tensions.
