In the context of increasing economic globalisation and geopolitical instability worldwide, international companies face complex challenges related to accessing new markets and complying with financial reporting standards. In this regard, the purpose of this chapter is to examine the impact of geopolitical changes on the international financial reporting system, with a particular focus on the harmonisation of accounting standards and how companies must adapt to new regulations in a multipolar economic environment. The chapter analyses how the geopolitical policies and strategies of emerging economic blocs can influence financial reporting and business sustainability. The major contribution of this research is the identification of new directions for the development of international financial reporting, particularly in the context of the decentralisation of global economies and the redefinition of global economic power.
