I think it's important to note that a China visa is required on most nationalities - TWOV isn't allowed on this fare, unless you can somehow squeeze a third country which includes Taiwan and HKG. That said, you have an option to add a stopover for CNY 1000 each, which is roughly US$150.
edit: Available ex-CRK starting in October, which isn't too far from MNL (~2hrs by car). The same fare basis works from MNL too but for some reason the base fare costs twice as much - it's still cheap though.
