Tensions between the Philippines and China have escalated over disputes in the South China Sea. Recent flashpoints include Chinese fishermen damaging the marine environment at Scarborough Shoal and Chinese ships firing water cannons at Philippine ships. The Philippines has accused China of causing the loss of giant clams in Huangyan Island, prompting calls for an environmental inquiry. The conflict has deepened with fears of 'cognitive warfare' and questions about how far the conflict will escalate.
