�A more assertive EU in a volatile world�

The predictions made last year with regard to the growing importance of great power rivalries still rings in our ears.

What is more, our strategic environment grows ever more unpredictable. Today, major powers openly challenge the rules based international order and seek to promote alternative visions of a world divided into spheres of influence. Geopolitical rivalry stokes tensions and raise the alarm bell of a new "proliferation age" that risk escalating into inadvertent military confrontation. Climate change is becoming an existential threat while cyberspace and disinformation campaigns are the new weapons of the 21st century

For the European Union, the answer is clear: these challenges can only be tackled through a multilateral approach. Together we have the tools and the political weight to shape the future global order if we stay united. This is why instead of retreating from international cooperation and global partnerships, the EU is stepping up its commitment to address global challenges together with its partners: this is true for the Paris agreement on climate change, the Joint Comprehensive Plan of Action (JCPOA) on non-proliferation, the 2030 Agenda for Sustainable Development, the EU's strategy for connectivity between Asia and Europe or the reform of the WTO.

While these agreements are - in essence - hard to reach, we are convinced they are the best way to ensure a more peaceful, prosperous and secure world environment. Even more so when it is clear that no single country can address these challenges alone. I am convinced this approach is the right one and the fact that demand for European action from our partners has never been so high speaks for itself.

At every given opportunity, the need to define common answers to common problems is not only highlighted but translated into action. The European Union is therefore investing in broader international cooperation and partnerships above all with NATO, the UN, and regional organisations such as the Africa Union and ASEAN. Our trilateral EU-AU-UN cooperation on common challenges such as migration illustrates how multilateral solutions can contribute to greater safety, stability and prosperity.

For instance, as the UN IPCC Special Report on Global Warming warned us recently, there is an urgent need to act on climate change. This is the logic for the EU's tireless efforts to reach a successful outcome at COP 24 in Katowice. The EU will lead by example by turning its own ambitious commitments for 2030 into concrete action. This was made clear at the high level event on Climate and Security hosted by the EU last June.

In the security sector, the European Union continues to assert its role as a security provider.Not only it is working internally to intensify joint efforts to effectively fight terrorism, hatred and violent extremism, the Union is engaged on the ground with 16 crisis management missions i.e. nearly 4.000 men and women. From building capacities in Mali, Niger and Central African Republic, to supporting security sector reform in Iraq, fighting piracy off the coast of Somalia or preventing a resurgence of violence in Georgia, the Union continues to strengthen international security in its neighbourhood and beyond. This is complemented by continued engagement in more than 40 mediation activities across the world, from Colombia to Yemen and Philippines, and underpinned by financial assistance as the EU remains the lead donor for development and humanitarian aid.

As Europe is taking more responsibility for its own security, the debate on European strategic autonomy has moved to the fore and not without controversy. However, at its heart is a simple reasoning: when needed, Europeans need to be able to protect and defend European interests and values and have the capacity to act. We want to be able to cooperate with third countries on our own terms.

In this respect, we stepped up the development of joint military capabilities through our 'Permanent Structured Cooperation' (PESCO), we will increase joint investments through the European Defence Fund, we are streamlining military command structures (MPCC), and we agreed a Compact to strengthen our civilian crisis management. As such these initiatives also contribute to strengthen NATO's European pillar and contribution to collective defence.

Greater responsibility also includes beefing up our own resilience and capacity in energy, space, infrastructure and other critical sectors. We Europeans cannot accept interference and destabilisation through hybrid and cyber-attacks, hence our on-going focus on reinforcing cybersecurity capacities, improving the protection of data and containing disinformation through the recently adopted Action Plan on Disinformation.

We also need to be extra vigilant to preserve achievements on non-proliferation, such as the INF treaty or the nuclear deal with Iran, as the stakes for our own security are simply too high. The starting point cannot be to dismantle the current architecture and start from scratch. We Europeans are working at all levels to promote the universalisation and implementation of existing agreements, such as the Nuclear Non Proliferation Treaty or the Hague Code of Conduct against Ballistic Missile Proliferation. We are also pushing for the Comprehensive Test Ban Treaty to come into force which could play an important role as we work towards a complete, verifiable and irreversible denuclearisation of the DPRK.

Taking greater responsibility does not stop at defence issues. Security today is also about economic security. This notion includes the strategic importance of the Euro and the need to ensure that the single currency can play its full role on the international scene. Promoting the Euro's international role is part of Europe's commitment to an open, multilateral and rules-based global economy. The extra-territorial effects of sanctions also challenge the Union's capacity to follow through on our own political commitments. In this context we are developing mechanisms that will assist, protect and reassure economic actors to pursue legitimate business abroad.

As Europeans we cannot afford to waste time or to be less innovative than others. We need to modernise our approaches and engage more actively with new actors at the intersection of technology and foreign and security policy. This is why the High Representative launched the Global Tech panel, with the CEO of major Tech companies, in order to help ensure that international ethics and rules can keep pace with human ingenuity. To harness these opportunities, we also must take the security implications seriously, hence the recent European Commission Communication on Artificial Intelligence.

All in all, supporting rules based multilateralism and greater European strategic autonomy are not contradictory objectives. If we strengthen our resilience in the face of new risks, the European Union will play its part in reinvigorating the multilateral order and be reckoned as an assertive actor in a volatile world.
