Opening up the G7 to South Korea to Address Contemporary Global Challenges
The G7’s global influence has diminished as powers like China reshape international governance through initiatives such as BRICS and the Shanghai Cooperation Organisation (SCO). With the G7 now representing just 10 per cent of the world’s population and 28 per cent of global GDP, its relevance is increasingly questioned.
Despite being poorly institutionalised, BRICS and SCO attract an increasing number of small and middle powers because they provide them with diplomatic influence they cannot obtain elsewhere. The G7 should draw inspiration from this and expand to include like-minded democracies, most notably South Korea. This would help counterbalance US dominance within the group, strengthen multilateralism and cooperation to address interconnected security cha lenges in Europe and the Indo-Pacific. Cooperation between G7 countries and South Korea is critical to uphold rules-based international trade, supply chain resilience and AI governance.
In 2026, France will assume the rotating presidency of the Group of Seven (G7). Fifty-one years after the first summit in Rambouillet – hosted by President Valéry Giscard d’Estaing) – the G7 itself has changed little (in 1977 it added Canada and in 1998 Russia, expelled in 2014 after its first invasion of Ukraine), yet the whole world around it has been utterly transformed.
UPDATING THE G7 TO THE REALITY OF THE CONTEMPORARY INTERNATIONAL CONTEXT
For decades, the G7 was synonym of a club of the world’s wealthiest countries. Now, the People’s Republic of China (PRC) is the world’s second-largest economy, and emerging powers such as India, Indonesia and Brazil are becoming heavyweights in the global economy. Competing international groupings are also gaining momentum, attracting a growing number of member states. The BRICS has expanded from its original five members (Brazil, Russia, India, China and South Africa) to ten, following the inclusion of four new countries in 2024 (Egypt, Ethiopia, Iran and the United Arab Emirates) and one in 2025 (Indonesia). Similarly, the Shanghai Cooperation Organisation (SCO), established in 2001 with six founding members (China and Russia plus four Central Asian states), has since grown to include India and Pakistan in 2018, and Iran and Belarus in 2023 and 2024, respectively – bringing its total membership to ten. To fully understand the reach of these organisations, it’s important to note that BRICS introduced a new category of “partner countries” in January 2025, officially encompassing nine states.1 Notably, during its most recent summit in Tianjin in September 2025, the SCO merged its “Observer” and “Dialogue Partner” statuses into a single “SCO Partners” category, now including seventeen countries spanning from Southeast Asia to the Near East.2

Center for Asian Studies
Asia is a nerve center for multiple global economic, political and security challenges. The Center for Asian Studies provides documented expertise and a platform for discussion on Asian issues to accompany decision makers and explain and contextualize developments in the region for the sake of a larger public dialogue.
The Center's research is organized along two major axes: relations between Asia's major powers and the rest of the world; and internal economic and social dynamics of Asian countries. The Center's research focuses primarily on China, Japan, India, Taiwan and the Indo-Pacific, but also covers Southeast Asia, the Korean peninsula and the Pacific Islands.
The Centre for Asian Studies maintains close institutional links with counterpart research institutes in Europe and Asia, and its researchers regularly carry out fieldwork in the region.
The Center organizes closed-door roundtables, expert-level seminars and a number of public events, including an Annual Conference, that welcome experts from Asia, Europe and the United States. The work of Center’s researchers, as well as that of their partners, is regularly published in the Center’s electronic journal Asie.Visions.

European Union-India: Lasting Rapprochement or Partnership of Convenience?
The partnership between the European Union (EU) and India has long been limited to economic exchanges. Its political dimension has gradually developed, culminating in its elevation to the status of a “strategic partnership” in 2004. However, the failure of negotiations for a free-trade agreement in 2013 slowed this momentum. Since the early 2020s, in an uncertain geopolitical context, bilateral rapprochement has gained new momentum.
Japan’s Takaichi Landslide: A New Face of Power
Prime Minister Sanae Takaichi has turned her exceptional popularity into a historic political victory. The snap elections of February 8 delivered an overwhelming majority for the Liberal Democratic Party (LDP), driven by strong support from young voters, drawn to her iconoclastic and dynamic image, and from conservative voters reassured by her vision of national assertiveness. This popularity lays the foundation for an ambitious strategy on both the domestic and international fronts.
The U.S. Policy Toward Taiwan Beyond Donald Trump: Mapping the American Stakeholders of U.S.-Taiwan Relations
Donald Trump’s return to the White House reintroduced acute uncertainty into the security commitment of the United States (U.S.) to Taiwan. Unlike President Joe Biden, who repeatedly stated the determination to defend Taiwan, President Trump refrains from commenting on the hypothetical U.S. response in the context of a cross-Strait crisis.
China’s Strategy Toward Pacific Island countries: Countering Taiwan and Western Influence
Over the past decade, China has deployed a diplomatic strategy toward the Pacific Island Countries (PICs). This strategy pursues two main objectives: countering Taiwan's diplomatic influence in the region and countering the influence of liberal democracies in what Beijing refers to as the "Global South."
