Radioactive Tide: Fallout From China’s Submarine Disaster Nears Philippines

In May 2024, China’s newest Zhou-class nuclear-powered attack submarine sank during mooring exercises at the Wuchang shipyard on the Yangtze River. Both main and backup motors failed, causing the vessel to submerge and release radioactive I-129 into the waterway. Beijing denied the incident and refused cooperation with the International Atomic Energy Agency (IAEA), attempting a cover-up.6l

By 2026, elevated I-129 levels—1.5 to 1.7 times higher than regional norms—reached the West Philippine Sea, impacting the Philippines’ exclusive economic zone. Scientists trace the radiation to Chinese nuclear activities, including the sub accident, via ocean currents.

Despite risks, Australian retailer Woolworths continues importing and canning Chinese seafood, prioritizing profits over potential contamination concerns.
