The trade relationship between the EU and China is long-established. It started officially in 1975 and, since then, the connections between the two parties have broadened and evolved, and so the interactions of the tax systems, sharpened by the soaring globalised economy and the intensification of digitalization. In this context, the e-commerce sector and the role of platforms that have fostered the growth of the latter raise questions about the adequacy of current tax rules. States have thus started rethinking their strategies for protecting their revenue. Both the EU and China promote a coordinated approach even towards exchanges of experiences to deal with tax matters this changing world is experiencing, and this is highlighted by the development and implementation of the BEPS as well as of the regulations regarding taxation of investments. Nevertheless, several issues –due to different approaches of the two parties– come to light and it seems necessary to untangle them in order to proceed on the taken root of cooperation.
