Today few people deny the existence of regional substate diplomacy (Criekemans 2010). But there is still no common agreement on a region's right to do so and, above all, on their scope of action. This question goes against what used to be the dominant approach in international relations, the state-centric approach that leads to the logic of speaking with one voice. Increasingly, a multilevel-governance approach has contested this state-centric view and proposes an alternative logic of multiple actors speaking with their voice, nuancing strongly the seminal distinction between "sovereignty-bound" and "sovereignty-free" actors (Rosenau 1990). From the 1970s, the world has seen the growing presence of sovereignty-free actors in international relations. Among these actors, non-central or, better, substate, governments of federal states have developed intensive foreign relations. These governments are using a range of techniques: from shaping the federal government's foreign policy to establishing themselves directly in the international arena (Blatter et al. 2008). For minority nation governments this is particularly a challenge, as they have to act internally – where they have developed full-fledged legislative powers within a multinational federation – and externally – where international and national laws are often still reluctant to recognise their right of action (Lejeune 2003). Yet some minority nations have thrived in developing their own international relations. Bavaria, Catalonia, Flanders, Quebec, Scotland and Wallonia are often seen as successful international players even if they are not fully sovereignty bound (Michelmann 2009; Criekemans 2010). The international actions of these minority nations have been characterised under the umbrella of "identity paradiplomacy" (Paquin 2003); that is, a willingness to use international relations to foster a nation-building process within a multinational state. This observation was particularly prevalent for minority nations strongly in competition with a federal government about their nationbuilding process, albeit for different reasons, namely Flanders, Quebec and Scotland (Paquin 2004). The case of Wallonia seems to fits less well into the identity paradiplomacy framework, which therefore raises the question of alternative roads to international relations. This is the core question of this chapter: is identity paradiplomacy the only way to go for minority nations? Quebec and Wallonia are both well known for their active foreign relations.

Although the new international economic
order (NIEO) has mostly been assessed as a failure, its
ideas still seem relevant in today's crisis environment.
The new context clearly shows that the existing liberal
international order is ineffective and calls for deep
changes like in the times of the developing countries'
fight for the NIEO. The article considers whether its
principles remain of relevance today, which ones have
been amended and which should be newly introduced,
all based on NIEO-related lessons. Dilemmas between
international law or a rules-based order as a framework for global governance and whether the proposed
new inclusive global economic order is to be based on
values (and if so, which) are evaluated.
