MANILA — Japan and the Philippines formally signed a Reciprocal Access Agreement on Saturday, granting each country's military personnel the right to enter the other's territory for training exercises and joint operations, in what officials described as the most significant bilateral defence milestone since the two nations normalised relations. Philippine President Ferdinand Marcos Jr. and Japanese Prime Minister Fumio Kishida's successor presided over the signing ceremony at Malacañang Palace, with foreign and defence ministers from both governments affixing their signatures to the accord.

The agreement, which has been under negotiation for over a year, allows Japan's Self-Defence Forces to operate from Philippine military installations in Luzon and Palawan — islands positioned directly adjacent to the disputed South China Sea. In return, Philippine armed forces will gain access to Japanese facilities and advanced training programmes, including maritime surveillance and anti-submarine warfare drills that Tokyo has developed over decades.

Senior officials from both governments were careful to frame the pact as a stabilising measure rather than a provocative one. 'This agreement is not directed at any third party,' the Philippine Secretary of National Defence said at a joint press conference following the signing. 'It reflects our shared commitment to a free and open Indo-Pacific and the rules-based international order.' Japanese defence ministry officials echoed the language, noting that the accord aligns with Tokyo's recently expanded security posture under its revised National Security Strategy.

Beijing responded swiftly, with the Chinese Foreign Ministry issuing a statement urging the two countries to 'refrain from actions that undermine regional peace and stability,' and warning that forming 'exclusive military blocs' risked escalating tensions in the South China Sea. The statement drew a pointed rebuttal from Manila, which noted that China's continued construction activity on disputed reefs in the Spratly Islands had necessitated deeper security partnerships.

Washington welcomed the agreement, with the US State Department calling it 'a landmark step that reinforces the strength of the alliance network in the Indo-Pacific.' The pact follows a pattern of tightening minilateral security ties in the region, including the Philippines' expanded access arrangements with the United States and Australia. Analysts noted that the Japan-Philippines accord effectively extends the reach of the US-anchored alliance architecture without requiring a formal new treaty, representing a model other regional partners are likely to study closely.
