The Philippine Coast Guard (PCG) on Thursday said it was monitoring three Chinese research vessels operating without authorization within the country’s exclusive economic zone (EEZ). The PCG spokesperson on the West Philippine Sea, Commodore Jay Tarriela, said two of the vessels, Zhuhaiyun and Xiang Yang Hong 10, were detected west of Luzon. In a separate statement, the PCG said the vessels’ activities prompted the Coast Guard Commandant, Adm. Ronnie Gil Gavan, to issue orders to intercept and challenge them.
