Background

China claims most of the South China Sea, overlapping with the claims of the Philippines, Vietnam, Malaysia, Brunei and Taiwan. In 2016, an international arbitral tribunal ruled that China's broad claims had no legal basis; China rejects the ruling.

Chinese coast guard and maritime militia vessels regularly confront Philippine ships, especially around Second Thomas Shoal and Scarborough Shoal, using water cannon and blocking manoeuvres. The sea is one of the world's busiest shipping routes.
