Japan takes Philippine fuel under a logistics pact for the first time

Japan and the Philippines began a six-day humanitarian drill on Sunday that applies their acquisition and cross-servicing agreement for the first time. The Philippine Air Force is to fuel a Japanese Air Self-Defense Force aircraft under the pact.

Defence minister Shinjiro Koizumi said on Friday that the exercise, Doshin-Bayanihan 6-26, would be the first use of the agreement, which took effect in August. He called that first use an important step, and said defence cooperation between the two countries had entered a new stage. The drill is framed as humanitarian assistance and disaster relief, not as a combat exercise. The thing being tested is the paperwork that lets one force hand fuel, ammunition or parts to the other without a fresh treaty each time.

Koizumi and Philippine defence secretary Gilberto Teodoro Jr met in Makati on 29 September, five days before the drill started. They agreed to set up a working group on equipment and technology transfer, the Philippine defence department said. The fuel transfer this week is the narrower, already-legal step. The working group is the one that would decide whether Japanese equipment follows the fuel.

What an ACSA actually changes

An acquisition and cross-servicing agreement is a logistics treaty. It authorises the sale, exchange or temporary transfer of supplies and services between two militaries. Japan has signed versions with the United States, Australia, Britain, Canada, France, India and Germany, among others. The Philippine text is the first with a Southeast Asian treaty ally of Washington. Until August, a Japanese crew that needed fuel at a Philippine field had to rely on a one-off arrangement or on US stocks. From this week, the Philippine Air Force can issue the fuel against the agreement, and Japan can return the favour at a Japanese base.

The quantity this week is one aircraft's fuel, in a disaster-relief scenario. The precedent is the point Koizumi marked. A first application is what later applications cite. If a typhoon, or a maritime incident, requires a larger transfer, the staff work done for Doshin-Bayanihan is the template. The agreement covers supplies and services. Fuel is the simplest item on that list, which is why it is the one being used first.

The map the drill sits on

Japan and the Philippines are both US allies, and both have maritime disputes with China, in the East China Sea and the South China Sea. Tokyo has increased patrols and coast-guard help to Manila over the past three years, and has discussed a reciprocal access agreement that would let troops train on each other's soil, a step beyond fuel. The ACSA is the logistics layer under that. It does not authorise Japanese combat aircraft to operate from Philippine bases in a war. It authorises the fuel that would make such a deployment possible if a separate decision were taken.

Koizumi did not say the drill was aimed at China. He said practical cooperation would continue. The location, the partner, and the month are enough to place it. A fuel transfer practised in the Philippines in October is usable in the same islands in a later month, for a mission the agreement does not name. Teodoro's public line has been that Manila will take practical help from partners who show up. A Japanese aircraft taking Philippine fuel is that line, written as a transaction.

The six days

The exercise runs to Friday. The public marker of success is small and checkable: a Japanese aircraft takes Philippine fuel, the paperwork clears, and both defence ministries say the clause was used. If that happens, the August agreement stops being a text and becomes a transaction. Teodoro's working group on equipment will still be meeting after the aircraft has gone. The fuel is the part that can be finished this week. Anything larger, a radar, a ship, a training detachment, waits on the working group that met in Makati on 29 September and has not yet published a list.
