BusinessWorld April 25, 2021 | 7:54 pm Reporter THE SOUTH China Sea is a major fish source for the Philippines that is crucial to its food security, political analysts said on Sunday, belying President Rodrigo R. Duterteâs claim that it couldnât quarrel with China over fish. Chinaâs unregulated fishing activities in the disputed waterway, where the Southeast Asian nation gets 27% of its fish catch, threatens the livelihood of thousands of Filipino fishermen, said Sheena A. Valenzuela, a national security analyst at the Ateneo De Manila University Policy Center in Manila. âItâs resources are crucial to the food security of Filipinos, contributing to coastal livelihoods and export trade,â she said in an e-mail. Chinaâs illegal fishing activities âcould also lead to the loss in livelihood of about 627,000 Filipino fishermen.â
