It attempts to answer two interrelated questions: from China's side, why Telefónica and from this operator's side, why China? China was looking for a reliable technology partner for its weak market segments and a bridge to Latin America. Telefónica ambitioned to expand its mobile customer base in a country with high growth potential (NYT) while reducing through economies of scale equipment supply costs in an oligopolistic market. The research adopts a case study methodology and focuses on the service operators China Unicom and Telefónica de España in the years after the dotcom crash and before the arrival of the Covid-19 pandemic. The investigation is based on sources from the companies involved and relevant documents from specialised institutions. The study finds that the need for cooperation in the knowledge and capital-intensive services and the coincidence in strategies led to the frame of international alliances of companies.35 p.application/pdfengcc-by-nc (c) Universitat de Barcelona, 2023https://creativecommons.org/licenses/by-nc/4.0/Sistemes de telecomunicacióXarxes de comunicacionsPolítica de la telecomunicacióXinaTelecommunication systemsCommunication networksTelecommunication policyChinainfo:eu-repo/semantics/article7372942023-07-07info:eu-repo/semantics/openAccess
