The Philippines launched a comic book on Friday in its fight against what it called distorted narratives about maritime rights in the disputed South China Sea, a move which drew criticism from China.

A Philippine security official says China is “pushing us to the wall” with growing aggression in the disputed South China Sea and warned that “all options are on the table” for Manila’s response, including new international lawsuits.

Experts however, warn that Manila’s strategy of having several warships patrolling at once could strain resources and leave the navy vulnerable to targeted attacks.
