In Europe, the question of borders is a central issue. According to the European Parliament, border regions cover around 40% of the European Union (EU) territory, concentrate 30% of its population and produce nearly a third of its gross domestic product.

These areas, long regarded as marginal, are now recognized as strategic, both for their economic importance and for the social, cultural, and political issues they raise. Once perceived as a strictly local or regional reality, life on the border is becoming a real subject of European policy. While situations vary from one border to another, they often highlight the structural challenges of integration: recognition of professional qualifications, cross-border access to social rights, and management of multilingualism.

It is from this perspective that the article addresses the border issue, focusing as much on concrete realities as on the imaginaries that traverse them. It first looks back at the gradual erasure of the materiality of internal borders, once lines of separation between states and symbols of sovereignty, which have been progressively reconfigured as spaces for cooperation within the European project. Driven by the ideal of unity, this process has transformed borders from obstacles into places of exchange and movement – at least in pro-European discourse. However, this symbol of integration is being undermined by a trend toward isolationism. While some borders are fading, others are being reinforced: external borders are becoming increasingly important. In contrast, internal borders remain benchmarks in the management of public policy and the structuring of national democracies.

The Study Committee on Franco-German Relations (Cerfa)
Accroche centre

The Study Committee on Franco-German Relations (Cerfa) was created in 1954 by an inter-governmental agreement between the Federal Republic of Germany and France, in order to raise awareness of Germany in France and analyze Franco-German relations, including in their European and international dimensions. In its conferences and seminars, which bring together experts, political leaders, senior decision-makers and representatives of civil society from both countries, Cerfa develops the Franco-German debate and stimulates political proposals. It regularly publishes studies through two collections: Cerfa notes and studies as well as Franco-German visions.

 

Cerfa maintains close relations with the network of German foundations and think tanks. In addition to its research and debate activities, Cerfa promotes the emergence of a new Franco-German generation through original cooperation programs. This is how in 2021-2022, Cerfa led a program on multilateralism with the Konrad Adenauer Foundation in Paris. This program is aimed at young professionals from both countries interested in the issues of multilateralism in the context of their activities. It covered a wide range of themes relating to multilateralism, such as international trade, health, human rights and migration, non-proliferation and disarmament. Previously, Cerfa had participated in the Franco-German future dialogue, co-led with the DGAP from 2007 to 2020, and supported by the Robert Bosch Foundation and the Daniel Vernet group (formerly the Franco-German Reflection Group) which was founded in 2014 upon the initiative of the Genshagen Foundation.

As a Catholic from the Rhineland, Friedrich Merz is heir to the CDU’s Franco-German policy, from Konrad Adenauer to Helmut Kohl and Wolfgang Schäuble. While Franco-German rhetoric and reflexes are deeply ingrained in him, their results must nevertheless be put into perspective.

The “Huawei Saga” in Europe Revisited: German Lessons for the Rollout of 6G

Date de publication

Accroche

While the European Union attempted to coordinate a collective response through its 5G Toolbox in Europe’s 5G infrastructure, member states diverged significantly in balancing political, economic, and technological considerations. Germany, despite its economic ties to China and status as Europe’s largest telecom market, only reached a tentative agreement in July 2024—one that appears largely symbolic.

France, the U.S. Oldest and Most Complicated Ally: A Stubborn Defender of a Truly European Industrial and Defence Policy

Date de publication

Accroche

France, the U.S.’ oldest ally, is also the EU country which most stubbornly defends genuinely European industrial and defence policies. It calls for ‘strategic autonomy’ in all political domains, a position increasingly difficult to hold against a hardening international climate.
