MANILA, Philippines — The Philippine Senate is moving to deepen the country’s international cooperation after Majority Leader Juan Miguel “Migz” Zubiri endorsed a package of seven international treaties and bilateral agreements covering aviation security, space activities, taxation, higher education and cross-border criminal justice.
Zubiri, who chairs the Senate Committee on Foreign Relations, presided over the committee hearing on Thursday, August 20, where lawmakers reviewed the agreements and their potential implications for the Philippines. The package cuts across areas that could affect everything from the safety of Filipino travelers and international students to tax coordination and the pursuit of fugitives abroad.
Seven agreements on the Senate table
The agreements reviewed by the committee include:
- Protocol to Amend the Convention on Offenses and Certain Other Acts Committed on Board Aircraft — aimed at strengthening the international legal framework governing offenses committed aboard aircraft.
- United Nations Convention on International Liability for Damage Caused by Space Objects — dealing with liability arising from damage caused by space objects.
- Philippines-Cambodia agreement on the avoidance of double taxation.
- Tax arrangement between the Manila Economic and Cultural Office (MECO) and the Taipei Economic and Cultural Office in the Philippines to eliminate double taxation and help prevent tax evasion.
- Asia-Pacific Regional Convention on the Recognition of Qualifications in Higher Education, commonly known as the Tokyo Convention, which addresses recognition of higher-education qualifications across participating countries.
- ASEAN Treaty on Extradition, designed to strengthen regional cooperation in dealing with persons wanted for criminal offenses.
- Philippines-India Treaty on Mutual Legal Assistance in Criminal Matters, establishing mechanisms for cooperation in criminal investigations and proceedings.
The Senate’s own treaty records show that the ASEAN Treaty on Extradition remains among agreements submitted for Senate concurrence in the current Congress, with the Foreign Relations Committee handling the matter.
Why the justice agreements matter
The extradition and mutual legal-assistance measures could become particularly significant as crimes increasingly cross national borders.
Mutual legal assistance treaties generally allow countries to cooperate in investigations and prosecutions by facilitating the exchange of evidence, documents and testimony and, where applicable, other forms of judicial assistance. Existing Philippine treaties demonstrate how such arrangements can help law-enforcement authorities pursue cases that extend beyond a single country’s jurisdiction.
The proposed Philippines-India mutual legal assistance treaty also comes amid a broader effort to strengthen Manila-New Delhi security and legal cooperation. During President Ferdinand Marcos Jr.’s state visit to India, the two governments included the criminal mutual legal assistance treaty among the agreements and outcomes connected with their strategic partnership.
The ASEAN extradition agreement, meanwhile, could provide another regional mechanism for dealing with fugitives and transnational criminal activity. That is distinct from mutual legal assistance: extradition concerns the surrender of individuals sought for prosecution or to serve sentences, while mutual legal assistance focuses primarily on cooperation in criminal investigations and proceedings.
Trade and taxation also part of the package
The Senate review is not limited to security and law enforcement.
The double-taxation agreements could affect cross-border economic activity by providing rules intended to prevent the same income from being taxed twice and by improving cooperation against tax evasion. That makes the agreements relevant not only to governments but also to businesses and individuals with income or economic interests spanning jurisdictions.
The inclusion of the Philippines-Taiwan tax arrangement is particularly notable because it involves the Manila Economic and Cultural Office and the Taipei Economic and Cultural Office in the Philippines, while the Philippines-Cambodia agreement broadens tax coordination with another Southeast Asian partner.
Education and aviation agreements add another layer
The higher-education agreement could also have practical consequences for Filipinos studying or seeking professional recognition elsewhere in the Asia-Pacific.
The Tokyo Convention focuses on the recognition of higher-education qualifications, potentially making academic credentials easier to assess across participating countries.
Meanwhile, the aviation protocol deals with offenses committed aboard aircraft — an increasingly important issue as international air travel connects more jurisdictions and creates situations in which determining legal authority can become complicated.
The space-liability convention addresses another emerging area: as satellite launches and commercial space activities expand, international rules are needed to determine responsibility when space objects cause damage.
Review is not the same as ratification
Despite the significance of the seven agreements, the Senate committee review does not by itself mean that all seven treaties have already been ratified by the Philippines.
Under Article VII, Section 21 of the 1987 Philippine Constitution, an international treaty or agreement is not valid and effective unless it receives the concurrence of at least two-thirds of all Senate members. Senate records have repeatedly reflected this constitutional requirement in the treaty-concurrence process.
The current committee hearings are therefore part of the legislative process that precedes possible Senate concurrence.
For Zubiri and the Foreign Relations Committee, the broader issue is whether these agreements strengthen the Philippines’ ability to work with other governments while protecting the country’s interests.
The seven measures collectively point to a broader foreign-policy agenda: tighter cooperation on security, smoother cross-border economic activity, greater mobility for students and professionals, and stronger tools against transnational crime.
And as more Filipinos, businesses and government institutions operate across borders, the impact of these agreements could extend well beyond the Senate chamber.
The next question is whether the seven agreements can secure the Senate votes needed to move from committee review to formal Philippine concurrence.
