American-aligned political forces in the country have recently increased their anti-China rhetoric with a couple of proposals. Concerning the first article, there was a similar bill that was drafted back in the mid 2000s but has been scrapped after China protested. I don't see this bill being approved while Duterte is still in power, but it is worthy to note that elections will be held May next year, so this is perhaps in preparation for the next possible American-sponsored politician that will replace Duterte. If only the 5+ million strong ethnic Chinese population in the Philippines are more politically active/involved, the US will have a harder time attempting to sway the elections in their favor.
If the next President is US sponsored, an invasion could be welcomed.
