In September 1991, the Philippine Senate rejected the bases treaty by a slim margin, and despite further efforts to salvage the situation, the two sides could not reach an agreement. As a result, the Philippine Government informed the U.S. on December 6, 1991, that it would have one year to complete withdrawal. That withdrawal went smoothly and was completed ahead of schedule, with the last U.S. forces departing on November 24, 1992. On departure, the U.S. Government turned over assets worth more than $1.3 billion to the Philippines, including an airport and ship-repair facility. Agencies formed by the Philippine Government have converted the former military bases for civilian commercial use, with Subic Bay serving as a flagship for that effort.
The post-U.S. bases era has seen U.S.-Philippine relations improved and broadened, with a prominent focus on economic and commercial ties while maintaining the importance of the security dimension. U.S. investment continues to play an important role in the Philippine economy, while a strong security relationship rests on the 1952 U.S.-Philippines Mutual Defense Treaty (MDT).
