Mecca Joint Defence Agreement: Cross-Regional Security Cooperation in a Fragmenting International Order

The Mecca Joint Defence Agreement between Pakistan, Turkey and Saudi Arabia represents an emerging form of cross-regional security cooperation amid growing geopolitical uncertainty. Despite their differing regional security environments and perceptions of threat, the three states have a sufficient convergence of security interests to institutionalise defence cooperation. This commentary argues that the agreement should not be viewed primarily as the creation of a new military bloc, but as an effort by regional powers to diversify their security options and exercise greater agency while retaining existing partnerships. At the same time, the flexibility of the arrangement presents both an opportunity and a constraint for its future operationalisation. The agreement therefore provides an important example of how regional powers are adapting their security strategies to a fragmenting international order, writes Ahyousha Khan. The author is a participant of the Valdai – New Generation project. 

On August 7, 2026, Turkey, Pakistan and Saudi Arabia signed the “Mecca Joint Defence Agreement” at the Summit of Joint Defence, which represents an emerging form of cross-regional security cooperation amid growing geopolitical uncertainty. It seeks to ensure “collective deterrence against any act of aggression”; the central question it raises is why three countries from three different geographical regions came together at this particular moment to sign it.

It can be argued that this agreement does not reflect the creation of a new military bloc; it represents an emerging form of cross-regional security cooperation through which regional powers are seeking to diversify their security options and exercise greater agency over the provision of security, while simultaneously retaining their existing partnerships in a fragmenting international order.

What Does it Include?

The official statements in the agreement declared it a “shield of peace”, assured it “does not constitute a threat to the security of any country in the region”, and described it as a “purely defensive” pact between three parties. Thus, the Mecca defence agreement is to provide a “collective deterrence” to signatories and it is built on the basis of “distinguished relations” and vows to address “a number of issues of mutual interest”. The most important clause of the agreement is that a threat against one would be regarded as a threat against all. Saudi Deputy Prime Minister for Public Diplomacy Rayed Krimly said the agreement “does not supersede or replace any existing bilateral or multilateral agreement between countries.” Thus, the agreement is defensive in nature, not against any state and is standing as an alternative pathway to security along with other existing pathways.

So, what is it that the agreement signifies?

The Mecca Joint Defence Agreement was signed in an environment of rising uncertainty at the global level, driven by increasing multipolarity and growing conflicts between states. The three signatories to the agreement are cross-regional players. Saudi Arabia is a Middle Eastern power, while Pakistan and Turkey, while belonging to different regions—South Asia and Eurasia respectively—are both geographically connected to and proximate to the Middle East.

Owing to their geographical proximity, shared membership in the OIC, and historical (socio, economic, political and military) ties, the three countries appear to have developed a degree of convergence in their vision of the regional security environment at this particular moment. However, it is also important to note that all three countries have different immediate security realities and threat perceptions. For Pakistan, the primary security concern remains its eastern frontier; for Saudi Arabia security concerns include the Houthis in Yemen, Iran, and the continuing repercussions of the Gaza war, while Turkey, as a NATO member, has its own alliance obligations and broader security concerns.

But what the Mecca pact does is institutionalise already existing bilateral relations. Thus, this agreement is taking bilateral cooperation to a trilateral level because of convergences on security and political matters at regional level between all three parties. Thus, in this regional environment it is important to understand that the Mecca security agreement is an attempt by three cross-regional powers to develop a joint security framework in order to attain security diversification for “all aspects of defence cooperation”. Although the agreement is considered a move towards attaining “strategic autonomy” by these cross-regional powers, its essence also lies in a trend towards diversification of security by enabling the three signatory countries to have “joint defence capabilities, strengthen strategic deterrence, enhance readiness and further develop and integrate their respective defence capabilities to jointly address any threats to their safety and security”.

Although this agreement is hailed as a move by regional powers to achieve “strategic autonomy”, it should not be mixed with the fact that by formulating the agreement, all three parties are formulating new pathway but are not rejecting any existing agreement. This means that Turkey’s NATO commitments would remain in place, Saudi Arabia would continue to maintain its security relationship with the United States, and Pakistan would not have to choose between its relationships with China, the United States, Russia, or other partners.

Question of Strategic Autonomy of Cross-Regional Powers

As the world is evolving in the direction of multipolarity, the pertinent question arising is how middle powers or regional power will ensure their security while maintaining relations with global powers. Currently, mid-sized and regional powers—particularly in the Middle East—are seeking greater agency in providing for their own security because of the vacuum left by the great powers. This perspective is important for understanding the agreement as a potential model of “strategic autonomy” for regional powers. Rather than relying solely on a global power or forming a rigid regional military bloc, the three states are pursuing a third option, which is a flexible, cross-regional security arrangement based on converging interests and aimed at strengthening collective deterrence against external aggression.

This arrangement allows these states to pursue greater security while maintaining their existing security options. Its flexibility leaves room for the possible inclusion of other states, such as Egypt, Qatar and Kuwait, while allowing the signatories to retain independent security and foreign policies. Unlike a rigid military bloc, such an arrangement can therefore expand cooperation without necessarily requiring states to abandon their existing partnerships or alignments. The flexibility that is the strength of the agreement is also a constraint because without formal obligations, it would be difficult but not impossible for the states to convert the security agreement into tangible dividend.

Conclusion

The signing of the agreement is the beginning of the process of institutionalisation of relations between three countries, but to take it a step further, the three partners will need to develop effective mechanisms for political consultation, military coordination, intelligence sharing, joint exercises and most importantly to improve interoperability as the three states possess different military structures, equipment and infrastructure.

The significance of the agreement, however, lies in how cross-regional powers are experimenting with new forms of security cooperation in an international environment where traditional assumptions about security are becoming uncertain.
