HONOLULU -- Recent events confirm that maritime territorial disputes in the South China Sea remain an issue for East Asian governments. Ownership of the Spratly Islands is claimed, in whole or in part, by Brunei, China, Malaysia, the Philippines, Taiwan and Vietnam.

In the first quarter of 2004 alone, the claimants took turns building up anxiety, raising concerns about the sustainability of the status quo and whether the 2002 Delaration on the Conduct of Parties in the South China Sea could ensure the claimants' self-restraint.

First came the Philippines' announcement of the Balikatan exercises with the United States in the South China Sea in February. The Philippine action appeared to be driven by Manila's growing uneasiness over an increasing number of visits by Chinese research vessels and warships in the Spratly Islands, as well as the sudden appearance of new Chinese markers on the unoccupied reefs late last year. The mounting tension did not dissipate until Philippine President Gloria Macapagal Arroyo assured the region that the military exercises did not have anything to do with the maritime territorial disputes.
