Not just that. They had also donated one Pohang Class Corvette to the Philippines. I hope that this 'donation' didn't contribute to such favorable bias for the Korean side. As you know, the North Koreans were able to sink a Pohang Class with relative impunity the last tragedy broke out. All hands died when the ship sank.
Too bad the Philippines cannot afford JMSDF's own Shirane Class Destroyers, which have a dedicated ASW capability. We have , unofficially, silenced many NorKor subs that had ventured into Japanese territory in the past with these ships.
