BEIJING: Philippine President Ferdinand Marcos Jr will summon China's ambassador in Manila, his office said on Tuesday (Jul 21), hours after Manila's envoy in Beijing was similarly summoned following accusations by both sides of provoking tensions in the contested South China Sea. Presidential Communications Undersecretary Claire Castro confirmed to reporters Marcos had summoned Chinese Ambassador Jing Quan at 5pm on Tuesday. The summoning of ambassadors comes a day after the Philippines and China accused each other of an encounter in the Second Thomas Shoal of the South China Sea. Philippine officials said one of its navy personnel was struck on the head but Beijing said Manila provoked the incident. Such diplomatic summons are relatively rare despite frequent tensions between China and the Philippines in the South China Sea.
