The Alpine Convention is the first example of an international treaty focusing on a transnational mountainous area. However, many of the issues dealt with in the Alpine Convention are of interest to other mountainous regions of the world. The Alpine Convention’s activities therefore include an "external aspect", which takes the form of direct or indirect support for or cooperation with relevant governance bodies in other mountainous regions of the world. This cooperation leads to a fruitful worldwide exchange of experiences and to the building of a global platform for representing the interests of mountainous regions. 

The cooperation between the Alpine Convention and other mountain ranges of the world is briefly presented below.

The Carpathian Convention
The Framework Convention on the Protection and Sustainable Development of the Carpathians ("The Carpathian Convention") was signed in 2003 by the Czech Republic, Hungary, Poland, Romania, Serbia, the Slovak Republic, and Ukraine and has been in force since 2006. Like the Alpine Convention, it consists of a framework convention and thematic protocols (on Biodiversity, Sustainable Forest Management, Sustainable Tourism, Sustainable Transport and Sustainable Agriculture and Rural Development). The initiative for the negotiations of the Carpathian Convention came from the UNEP Regional Office for Europe (ROE), which also hosts the interim Secretariat of the Convention. 

The Alpine Convention States (in particular Italy and Austria) played an active role in the process of establishing the Carpathian Convention following an "Alpine-Carpathian partnership" that was launched during the UN International Year of the Mountains 2002. On 13 December 2006, the presidencies and secretariats of the Alpine and Carpathian Conventions signed a Memorandum of Understanding. The two secretariats cooperate regularly and reciprocally attend meetings.

The Pyrenees
The Pyrenees represent a very important landscape and biodiversity reservoir shared by three States (Andorra, France, Spain). The Pyrenean Climate Change Observatory was set up in January 2010 by the Working Community of the Pyrenees with the main aim of following and understanding the climate evolution in the Pyrenees, limiting its impacts, and providing adaptation to its effects through adaptation strategies for socio-economic sectors and the most fragile natural areas. The Permanent Secretariat of the Alpine Convention is a member of the Advisory Board of the Pyrenean Climate Change Observatory. Both organisations cooperate through joint projects and events. 

Hindu Kush Himalaya
Intergovernmental cooperation is picking up speed in the Hindu Kush Himalaya (HKH) region, led by ICIMOD (International Centre for Integrated Mountain Development). ICIMOD is an intergovernmental knowledge and learning centre of the eight HKH countries (Afghanistan, Bangladesh, Bhutan, China, India, Myanmar, Nepal, and Pakistan) and has existed since 1983.

ICIMOD organised the first HKH Science-Policy forum in 2018, then published the Hindu Kush Himalaya Assessment in 2019, a collection of scientific research about mountain issues and the HKH specifically, as well as offering insights for policymakers. A year later, ICIMOD published the HKH Call for Action, based on the Assessment, outlining six urgent actions to take for sustainable mountain development in the region. Following this, the first Hindu Kush Himalaya Ministerial Mountain Summit took place in 2020 "to further the mountain agenda of a prosperous, peaceful, and poverty-free HKH." To continue and strengthen this cooperation, a High-Level Task Force was mandated to assess the feasibility of establishing a regional institutional mechanism for the HKH. The Task Force is coordinated by ICIMOD.

In 2022, the Permanent Secretariat and ICIMOD organised a joint webinar as well as a study visit of members of the Task Force and ICIMOD to Innsbruck, to share information and discuss issues of transnational mountain governance and sustainable development. Cooperation for awareness-raising on mountain issues is also ongoing.

Andes
The Andean Mountain Initiative, gathering Argentina, Bolivia, Colombia, Chile, Ecuador, Perú and Venezuela, was established in 2007 to promote sustainable development in the mountain areas of the sub-region. The founding Tucumán Declaration was officially presented to the Permanent Committee of the Alpine Conference and contacts have been maintained over the years.

In 2023, the Permanent Secretariat and the Slovenian Presidency hosted a delegation from the Andean Mountain Initiative in Innsbruck and in Slovenia to discuss the respective experiences of regional and cross-border cooperation in the Alps and the Andes. The Andean delegates also attended the 76^th meeting of the Permanent Committee of the Alpine Conference, as well as the 14^th meeting of the Carpathian Convention Implementation Committee.

Following their visit, the Andean Mountain Initiative produced a ‘Mountains Connect Brief: Experience exchange between the Andes, Alps and Carpathians’, highlighting the key takeaways and lessons from the visit.

Resolution by the Dinaric States
The Alpine Conference of 2006 declared The Western Balkans to be an area of “priority importance for cooperation” for the Alpine Convention on the initiative of Italy. Under the Slovenian Presidency in 2009, a process was launched with a view to achieving a common declaration. 

A common Resolution by the Dinaric States ("on the sustainable development of the Dinaric arc region") was negotiated in 2010 and approved on 9 March 2011 by the Ministers or High representatives of Albania, Croatia, Former Yugoslavian Republic of Macedonia, Kosovo, Montenegro and Slovenia on the side of the XI Alpine Conference. This Resolution intended to pave the way to a possible future instrument of international law, similar to the Alpine and Carpathian Conventions. 

Caucasus Mountain Co-operation
The Caucasus mountain range links together two seas on a territory with unique geological and environmental characteristics. With the aim of environmental protection and support for the sustainable development, the Caucasus countries (Armenia, Azerbaijan, Georgia, Iran, the Russian Federation and Turkey) came together with a meeting of the Authorised Representatives on the Development of a Legal Instrument for the Protection of the Caucasus Mountain Ecosystem in 2001 where a resolution recognising the need for a legal instrument was signed. 

One of the first steps towards cooperation in the Caucasus region was made through forming synergies between existing projects and fostering multilateral partnerships for mountain issues within the region as well as with the other mountain regions of the world. The project "Sustainable development of mountainous regions of Caucasus" was launched, inspired by the Alliance in the Alps network and financially supported by some Alpine countries, with a goal of providing a draft for development programmes for eight mountain villages. 

Central Asia
Mountain partnership in the Central Asia started in 2000 with the establishment of The Central Asian Mountain Partnership (CAMP) in Kyrgyzstan, Tajikistan, and Kazakhstan. The main aim of the project was to promote sustainable mountain development to ensure better living conditions for poor majority of mountain people. In the first phases CAMP was working in four main areas: resource use, product development and marketing, village development, and policy dialogue. In 2003 CAMP established the Alliance of Central Asian Mountain Communities (AGOCA), after the model of "Alliance in the Alps", as a network of mountain communities with a goal of promoting the interests of the mountain communities, improve communication between mountain villages and exchange of knowledge and experiences. AGOCA today comprises 70 participating villages and is the reference organisation for coordinating transboundary cooperation projects. 

The Permanent Secretariat of the Alpine Convention has cooperated in the past with CAMP and AGOCA and some of the Alpine Convention governments finance specific small-scale projects in Kyrgyzstan, Tajikistan, and Kazakhstan. 

Despite their geographical diversity, mountain regions worldwide also show great similarities in their challenges. Therefore, the Alpine Convention acts in a spirit of cooperation with several partners around the globe to exchange experiences and to raise awareness on the specificities of mountainous regions. This transcontinental cooperation contributes to the goal of protecting a balanced and sustainable development of mountain areas.

The international dimension of the Alpine Convention is briefly outlined below.

United Nations Framework Convention on Climate Change
The Alpine Convention has been active within the UNFCCC framework in order to raise the awareness of climate negotiators of the particular vulnerability of mountains to climate change and their specific solutions. Contracting Parties and the Permanent Secretariat, in cooperation with other mountain areas of the world, have been organising or participating in side events dedicated to mountains in most sessions of the COP since 2011. The Secretary Generals have also delivered several speeches in the high-level segment.

Convention on Biological Diversity
In 2018, the Convention on Biological Diversity (CBD) celebrated 25 years of “safeguarding life on Earth”. The CBD promotes nature and human wellbeing and is structured according to the following three main objectives:

1. conservation of biological diversity;
2. sustainable use of the components of biological diversity;
3. fair and equitable sharing of the benefits arising out of the utilisation of genetic resources.

The world’s mountains are hotspots of biodiversity and home to many unique and rare species. Cooperating at international level to address the threats to this precious mountain biodiversity is crucial, which is why the Alpine Convention has signed a trilateral Memorandum of Cooperation (MoC) with the Convention on Biological Diversity (CBD) and the Carpathian Convention. The first MoC was signed in 2008 to facilitate the exchange of information and experience between the parties and to formalise their collaboration. Following several successful years of cooperation, a new MoC was signed in 2023 to reflect the new Kunming-Montreal Global Biodiversity Framework and the will of the three Conventions to enhance the synergies between them and their common activities.

Mountain Partnership
The Mountain Partnership was set up as a “Partnership type-2” in the framework of the Johannesburg World Summit on Sustainable Development as a voluntary alliance with the objective of creating a platform for cooperation among all states, organisations, and NGOs interested in sustainable mountain protection. The legal basis for its establishment are Article 13 of Agenda 21 and Article 42 of the Johannesburg Action Plan. It currently includes 50 governments, 16 intergovernmental organisations, and 143 major groups (e.g. civil society, NGOs, and the private sector) including the Alpine Convention. Its Secretariat is hosted by the Food and Agriculture Organization of the United Nations (FAO) in Rome (IT).

Each year on 11 December, the Permanent Secretariat of the Alpine Convention celebrates International Mountain Day by organising the cultural and literary Reading Mountains Festival.

European Environment Agency
In 2012, a partnership agreement was signed between the European Environment Agency (EEA) and the Permanent Secretariat of the Alpine Convention. This is implemented via two-year work programmes. A close cooperation is pursued in data collection and data sharing, contributions to publications, networking, and dissemination of activities. The latter aims at fostering exchanges between European transnational regions and mountain conventions on environmental observation and information. To this end, the EEA collects and harmonises national data, supported by the EIONET network (European Environmental Information and Observation Network).

The Permanent Secretariat of the Alpine Convention is actively involved in the Climate Adaptation Platform Climate-ADAPT, which is maintained by the EEA. The manifold common topics, with a focus on climate change, and the need for data sharing makes the cooperation with the EEA and EIONET particularly important.

Forest Europe Process 
In 2009 the Permanent Secretariat of the Alpine Convention obtained observer status to the Forest Europe Process.
