The diplomatic dispute between the United States, China, and Argentina regarding Chinese technology in the Vaca Muerta energy region has intensified. The conflict centers on the Neuquén-based electric cooperative CALF, which seeks to partner with Huawei for fiber optic and electrical infrastructure. U.S. Ambassador Peter Lamelas escalated the tension during the AmCham Energy Forum, warning that Huawei’s presence in critical infrastructure could compromise national security and deter international investment. Lamelas asserted that China requires its companies to provide the state with access to data passing through their technology and AI networks. In response, the Chinese Embassy rejected these claims as ‘baseless slander’ and accused Washington of employing a ‘Cold War mentality’ to sow market fear, defending Huawei’s cybersecurity record and its commitment to ‘no backdoor’ agreements. The dispute follows reports that U.S. officials warned CALF executives that maintaining ties with Huawei could result in the revocation of visas. ~~A U.S. official reportedly contacted a CALF manager via WhatsApp to warn of~~ CALF’s general secretary, Yenny Fonfach, characterized these ~~potential visa restrictions.

Further reports indicate the U.S. may restrict or revoke visas for 18 top executives, including President Marcelo Severini, if negotiations with Huawei proceed. Lamelas defended these actions as ‘private diplomatic management’ ~~intended to protect U.S. national~~ and a ‘national security ~~interests.~~ issue.’ The Chinese Embassy condemned the move as ‘visa blackmail’ and an infringement on Argentine sovereignty. In a significant escalation, the Argentine Chamber of Deputies has formally summoned Ambassador Lamelas to testify before the Commission on Cooperative, Mutual, and Non-Governmental Organizations. Deputy Aldo Leiva, president of the Commission on Cooperative Affairs, scheduled a hearing for August 19 to address allegations that diplomatic channels were used to influence local commercial decisions and interfere with CALF’s technological autonomy.
