A Philippine boat convoy carrying supplies for Filipino fishers returned to port after being shadowed by a Chinese vessel, aborting their plans to assert Philippine rights in the South China Sea. The convoy, escorted by a Philippine Coast Guard vessel, had set out to distribute fuel and food to fishers and was shadowed by 19 Chinese vessels, including a warship and eight coast guard vessels, around Scarborough Shoal. The Chinese embassy in Manila responded by warning against any attempt to infringe on China's sovereignty over the shoal.
