Philippine pact gives US access to air, sea bases

Obama backs Manila's decision to seek int'l arbitration of territorial dispute

The US-Philippine Enhanced Defense Cooperation Agreement was signed on Monday at the Defense Ministry in Manila shortly before Obama's arrival on the last stop of his four-country Asian tour.
