US, Japan, Australia and the Philippines pledge a combined coordination centre on Philippine soil

The defence ministers of the United States, Japan, Australia and the Philippines have committed to setting up a Combined Coordination Center in the Philippines, according to a joint statement published on 10 November 2026 by the office of Australia's defence minister. The statement records a four-way meeting held on 28 October in Cebu on the sidelines of the ASEAN Defence Ministers' Meeting-Plus, attended by US Secretary of War Pete Hegseth, Australian Deputy Prime Minister and Defence Minister Richard Marles, Japanese Defence Minister Shinjiro Koizumi and Philippine Defence Secretary Gilberto Teodoro Jr.

The centre heads a short list of what the ministers called forward-looking initiatives. Alongside it, the four governments said they would synchronise their defence investments to support the Philippines in defending its archipelago, strengthen consultations at ministerial and senior policy level, and expand the scope, complexity and frequency of their combined exercises and other cooperative activities.

The ministers said those steps would build on recent progress, which they listed as the newly signed terms of reference for a Pacific Chiefs of Defense Cooperation Council and the exercises Balikatan and Keen Sword, together with their regular maritime cooperative activities. They also restated serious concern about the situations in the East China Sea and the South China Sea and their strong opposition to any unilateral action, including by force or coercion, that raises tensions in the region.

The Philippine Department of National Defense put out the statement in Manila on the same day, BusinessWorld reported, describing the centre as a way to improve military coordination among the four countries and to support the defence of the Philippines. The Liberty Times in Taipei, citing Bloomberg, said the agreement comes as tension between Manila and Beijing over the South China Sea stays high and as President Ferdinand Marcos Jr. deepens defence ties with Washington, Tokyo and Canberra to narrow the military gap with China.

The timing also puts the pledge just ahead of a crowded diplomatic calendar. The Liberty Times noted that US President Donald Trump is expected in Manila within days for the annual ASEAN summit before travelling on to China for talks with Xi Jinping.

A coordination centre of the same name is not entirely new. In May 2026, at the close of Exercise Balikatan, Philippine and US commanders described a newly established Combined Coordination Center inside Camp Aguinaldo in Quezon City as a secure multinational command-and-control hub that uses encrypted networks shared among allies, according to Inquirer.net. Armed Forces chief General Romeo Brawner Jr. said at the time that Marcos had watched a live-fire drill in Ilocos through the facility alongside personnel from the US, Australia, France, Canada and Japan, and that the next aim was to link it with allied command centres in Japan, Australia and US Indo-Pacific Command.

The ministerial statement does not say whether its commitment means formalising that Camp Aguinaldo facility as a four-nation body, enlarging it, or creating a separate site. It also gives no timetable, staffing plan or budget for the centre, so the practical difference from the existing arrangements remains to be seen.

For Taiwan, the significance lies in geography. The northern Philippines faces Taiwan across the Luzon Strait, and a standing hub through which the four allies plan exercises, share communications and coordinate investment in Philippine defences would give them a common node close to the island's southern approaches, at a time when all four governments say they are seriously concerned about the security situation in both the East China Sea and the South China Sea.
