On the territory of which country was MV Doña Paz, a passenger ferry, found after sinking?

MV Doña Paz was a Philippine-registered passenger ferry that sank after colliding with the oil tanker MT Vector on December 20, 1987. Built by Onomichi Zosen of Hiroshima, Japan, the ship was launched on April 25, 1963 as the Himeyuri Maru, with a passenger capacity of 608. In October 1975, the Himeyuri Maru was bought by Sulpicio Lines and renamed as the MV Don Sulpicio. After a fire incident occurred on board in June 1979, the ship was refurbished and renamed as the MV Doña Paz.

Traveling from Leyte island to the Philippine capital of Manila, the vessel was seriously overcrowded, with at least 2,000 passengers not listed on the manifest. Additionally, it was claimed that the ship did not have a radio and that the life-jackets were locked away. However, official blame was directed at Vector, which was found to be unseaworthy, and operating without a license, lookout or qualified master. With an estimated death toll of 4,386 people and only 25 survivors, it remains the deadliest peacetime maritime disaster in history.
