Philippines Looks to US Treaty in China Dispute

A tense naval standoff stemming from competing territorial claims between China and the Philippines is throwing a spotlight on an obscure treaty between Manila and Washington. But contemporary political considerations may trump the decades-old agreement.

The Mutual Defense Treaty between the United States and the Philippines is being dusted off in both Washington and Manila by diplomats and politicians, many of whom were not even born when it was written in 1951.

Officials are trying to determine whether the United States is compelled to come to the aid of Manila should there be a military clash between the Philippines and China in an isolated lagoon some 200 kilometers west of Subic Bay.
