The 2+2 Ministerial Dialogue is a bilateral diplomatic concept and institutionalized mechanism that brings together the Foreign and Defence Ministers of two countries to coordinate on strategic, security, and defense matters. For India, the dialogue involves the Minister of External Affairs and the Minister of Defence meeting with their respective counterparts from a partner nation.
The dialogue was initially established with the United States, replacing the earlier Strategic and Commercial Dialogue that began under the Obama administration. The agreement to create the India-US 2+2 Dialogue was reached during Prime Minister Narendra Modi's visit to the US in June 2017, and the inaugural meeting took place in New Delhi on September 6, 2018. The purpose was to elevate the strategic consultations and promote synergy in diplomatic and security efforts, putting the strategic, defense, and security relationship at the forefront.
The mechanism works by having the four ministers—two from each country—meet, typically on an annual basis, to review progress on prior commitments and issue joint statements detailing outcomes. Key provisions and outcomes often include signing foundational defense agreements, such as the Communications Compatibility and Security Agreement (COMCASA) signed during the first India-US dialogue, which facilitates interoperability and access to secured US military technology. The dialogue also focuses on regional and global issues, including cooperation in the Indo-Pacific region and counter-terrorism efforts.
The 2+2 Dialogue connects to India's broader strategic partnerships, particularly with members of the Quad (Quadrilateral Security Dialogue). India has expanded this format to include other key partners: the first India-Japan 2+2 meeting was held in 2019, the first India-Australia 2+2 meeting was held in September 2021, and the first India-Russia 2+2 meeting was held in December 2021. More recently, the inaugural India-UK 2+2 Foreign and Defence Dialogue was held in October 2023 at the official level. The core structure of the dialogue—involving the Foreign and Defence Ministers—has stayed the same, but the number of countries India engages with in this format has expanded significantly since 2018.
