''Both, according to PRRD ( President Rodrigo Roa Duterte) must promote counter-narratives to address the message of hate and destruction propagated by violent extremists and terrorists, '' said Panelo.

Duterte also expressed his appreciation '' for the actions taken, with the assistance of the UN, to build resilience and strengthen the support for climate change adaptation and mitigation in a region where natural disasters occur frequently.'', said Panelo. DMS
