Turkey and Qatar signed a mutual defence agreement on Friday, marking a significant escalation in their security cooperation. Turkish President Recep Tayyip Erdogan and Qatari Emir Sheikh Tamim bin Hamad al-Thani formalized the accord during a meeting in Istanbul, according to a joint statement reported by Al-Monitor and France 24. The agreement commits both nations to a unified position against any external armed attack targeting either country. The leaders met in the Turkish city after the Qatari Emir attended the United Nations COP31 climate summit in southern Turkey, as reported by Asharq Al-Awsat.

The pact, reached during the 12th session of their Supreme Strategic Committee, aims to bolster collective defence and promote regional stability. Turkey and Qatar agreed to consult on threats to their security, as well as broader regional and global security issues. The joint statement, cited by multiple outlets, outlined plans to expand cooperation through joint military exercises, defence-industry collaboration, and the exchange of personnel training. The agreement reflects a shared commitment to safeguarding sovereignty and territorial integrity, the leaders stated in their communique.

Beyond military ties, the two nations expressed readiness to deepen energy cooperation, particularly in liquefied natural gas trade. The Turkish presidency noted that both countries are working to develop and diversify their energy partnership. This economic dimension complements the security framework, building on a long-standing relationship between the two regional allies. Erdogan stated that the mutual defence agreement would add a new dimension to the brotherly ties between the nations, according to his office.

The signing follows a broader trend of regional defence pacts. In August, Turkey, Saudi Arabia, and Pakistan signed the Mecca Joint Defence Agreement, which was ratified by the Turkish parliament last week. That pact obligates the three countries to assist one another if any member faces an attack. The new Turkey-Qatar accord mirrors this structure, potentially creating a network of allied defence commitments in the Gulf region. The Turkish presidency emphasized that the agreement would help prevent the resurgence of war in the Gulf and establish a basis for dialogue and peace.
