This thesis discusses how ideas, as domestic factors, have decided the formation of China’smultilateralist foreign policy. It tries to provide an profound understanding of China's foreignpolicy development with the theoretical tools provided by discursive institutionalism andhistorical institutionalism.Three empirical cases are studied: the case of WTO, the case of ASEAN+3 and the case ofShanghai Cooperation Organization (SCO). These three cases have represented China'sinvolvement of multilateral institutions at different time and level.The findings show that China has gradually turned to an active participants of multilateralinstitutions, and it is trying to constructing a new type of multilateralism: competitivemultilateralism. Whether it can be compatible with existing institutions is an open question. / Doctorat en Sciences politiques et sociales / info:eu-repo/semantics/nonPublished

[pt] Após a crise financeira e econômica de 2008, países emergentes buscaram traduzir seu novo peso econômico em influência política. Instituições tradicionais criadas após a II Guerra Mundial, em particular nas esferas econômicas e financeiras, não mais representativas do cenário econômico mundial, seriam questionadas por economias emergentes. China, Índia, Brasil, Rússia e África do Sul (os BRICS) defenderam a adoção de reformas à estrutura institucional da ordem mundial liberal, as quais não foram totalmente alcançadas. Essa dissertação analisa o engajamento dos países emergentes a ordem mundial após a crise de 2008, particularmente em relação à governança econômica e financeira. O argumento central baseia-se na percepção de que países emergentes vêm, desde a crise de 2008, articulando maneiras de impactar a atual ordem liberal mundial, como compreendido pelo conceito de mundo multiplex, desenvolvido por Amitav Acharya (2014; 2017). Ao longo da análise da nova posição dos países emergentes na ordem mundial, por meio de uma discussão do fortalecimento do seu papel em fóruns como o G20 e a criação de grupos como o do BRICS, essa dissertação tratará de dois estudos de caso: (i) a criação do Novo Banco de Desenvolvimento, em 2014, por Brasil, Rússia, Índia, China e África do Sul, e; (ii) a criação do Banco Asiático de Infraestrutura e Investimento, em 2015, por iniciativa da China. / [en] After the 2008 financial and economic crises, emerging countries channeled their newly found economic resilience into political leverage. Traditional institutions created after World War II, particularly those in the economic and financial spheres, which were no longer representative of the new economic setting, would be questioned by emerging economies. China, India, Brazil, Russia and South Africa (the BRICS) have championed reforms to the institutional structure of the liberal world order, which have not been entirely met. This dissertation aims to shed light on the engagement of emerging countries in world order after the 2008 crisis, particularly in the economic and financial global governance. The main argument is that emerging countries have, since the 2008 crisis, been articulating ways to impact the current liberal world order as captured by the concept of multiplex world, developed by Amitav Acharya (2014, 2017). Along the analyses of the current greater role of developing countries in world order, through a discussion of the new found role of forums such as the G20 and the creation of groups such as the BRICS, the dissertation will focus on two case studies: (i) the creation of the New Development Bank, in 2014 by the Brazil, Russia, India, China and South Africa, and; (ii) the creation of the Asian Infrastructure Investment Bank, in 2015 fostered by China.

The liberal theory of international relations primarily associates international cooperation with liberal democratic states, to the point that a theory of scholars Poast and Urpelainen claim that international cooperation with consolidated democracies through international organizations may boost the democratization of or at least prevent democratic backsliding in non-consolidated democracies. This paper investigates the possibility of decoupling these theories from democracies and democratizing by examining whether Chinese efforts within the framework of the Asian Infrastructure Investment Bank and the Belt and Road foreign policy project have a similar but reverse effect on its target states, prompting developments in authoritarian directions. Though the results of study are inconclusive on account of the relative youth of the studied IOs, they indicate a strong possibility that could do with further study.
