My friend the Filipinos took the Mount Pinatubo explosion as some kind of Divine revelation of how G_d did not want the Gaijin America soldiers to be in the country. Hence the expulsion of the US Forces in 1992.
As soon as the Americans were out and as soon as there was reduced American naval presence in the SCS, which the Filipinos had relied so heavily on American naval support to do their territorial passex, this ultimately was taken advantaged upon by the Vietnamese AND the Chinese who increased their military presence in the SCS area. It is not only the Chinese who increased militarized presence in the SCS post-Subic Bay epoch, but the Vietnamese. In fact it was the Vietnamese who had clashed with Filipino marines than Chinese, to be historically accurate.
So then in 1997 the Filipino Congress went begging their president at the time , Fidel Ramos, to contact the United States Pacific Command to 'reorganize' the relationship between Washington and Manila in the 1997 VFA [Visiting Forces Agreement]. In other words they reneged on their 1992 senate-wide declaration of having no foreign military bases or foreign soldiers based on Filipina soil.
And here were are now in 2015.
Politics, isn't it just a funny , wet , little lady? lol. Love it.
