Around 250 Chinese fishing vessels were detected by Peruvian naval forces some 230 miles (370.15 km) off the coast of Peru, sparking a Twitter war between Washington and Beijing.

According to a US marine biology expert, China's illegal construction of artificial islands and overfishing possibly damage ecosystems as well as deplete seafood resources in the South China Sea (Bien Dong Sea).

A fishing fleet of China is under the surveillance of Ecuador's navy over concerns about impacts on the environment in the ecologically sensitive islands.
