Philippine President Rodrigo Duterte will go to war with China if it crosses ‘red lines’ and claims disputed resources, foreign ministry warns
Foreign Secretary Alan Peter Cayetano said that China trying to extract oil and gas from the South China Sea was one of several actions Duterte forbade

The Philippines has warned China that it will go to war over natural resources in the South China Sea – and it identified other “red lines”, or actions, Manila would find unacceptable, the foreign ministry said on Monday.
Foreign Secretary Alan Peter Cayetano said that among the territorial issues discussed with China were construction activities at a disputed shoal and the unilateral extraction of oil and gas in the South China Sea.
“Nobody can extract natural resources there on their own,” Cayetano said. “The president has declared that. If anyone gets the natural resources in the West Philippine Sea-South China Sea, he will go to war.”
Critics and left-wing groups have slammed President Rodrigo Duterte for not publicly raising the alarm over recent Chinese actions, including the reported installation of missile defence systems on its newly constructed islands.
