Commentary 1
What can we learn from China’s military aid in the Pacific?

This WritePeace blog explores data and trends in China’s military aid to Pacific island countries over the past two decades. It concludes that although China evidently has ambitions to expand its military reach in the Pacific, it would be premature to call it a regional military power. China’s military aid to Pacific island countries has diversified in recent years, but remains trivial in both volume and substance. So far, the mounting economic and political influence China has gained through development aid, infrastructure loans and trade poses a bigger challenge to the geopolitical status quo in the Pacific than its military activities.

Commentary 2
Taking climate security forward in the OSCE

There is growing international recognition that climate change impacts and security challenges—along with their solutions—are increasingly linked. This WritePeace blog summarizes how the Organization for Security and Co-operation in Europe (OSCE) is working on climate security. It discusses the implications of a decision adopted at an OSCE Ministerial Council meeting in Stockholm last year on ‘strengthening co-operation to address the challenges caused by climate change’, and looks at ways that the organization could build on this new momentum.

Commentary 3
We must strengthen multilateralism in a new era of risk

In this SIPRI Essay, Stefan Löfven and Margot Wallström address the failure of global governance to address contemporary challenges. Linking to SIPRI’s Environment of Peace report and the Stockholm+50 conference, the essay focuses on the twin environmental and security crises that have brought us into a new era of risk to human security. There is now no choice but to tackle them. These new risks require collective action and strengthened global governance. This in turn requires inclusivity, dialogue, financial solidarity, transparency and a change to the narrative.

Commentary 5
In a time of competing crises, environmental action matters more than ever

In this SIPRI Essay, the lead authors of SIPRI’s Environment of Peace report underline that although recent events have renewed focus on ‘hard’ security issues like armaments, nuclear weapons and military alliances, the wider situation illustrates that interactions between the twin crises in security and the environment are creating new, complex risks that can cascade around the world. Recent circumstances have tested global resilience. However, the authors argue that these difficult circumstances should not be seen as a reason to postpone dealing with the environmental crisis.

Towards an Integrated Approach to Climate Security and Peacebuilding in Somalia

Climate change and its security implications are placing considerable pressures on peacebuilding efforts in Somalia. Analysing the leading climate-related security risks in Somalia and identifying gaps in existing responses lead to a new approach to integrate climate security and peacebuilding in Somalia. The three components of this approach are environmental peacebuilding, national governance and international support. This report argues that, together, these components can help to integrate responses to climate, peace and security in Somalia and strengthen the capacity to implement them.

Revisiting ‘Minimal Nuclear Deterrence’: Laying the Ground for Multilateral Nuclear Disarmament
This paper starts from the assumption that many insights from previous minimal nuclear deterrence discussions are still valid and can help to invigorate the current debate on practical approaches to disarmament. The paper argues that nuclear deterrence is possible at low numbers, and hence reliance on nuclear deterrence is not an obstacle to significant progress in nuclear disarmament. In particular, there is scope for reducing the vast nuclear arsenals possessed by Russia and the United States, which risk planetary-scale destruction and stand in the way of multilateral nuclear disarmament.
