Mundo Obrero (“Workers’ World”) is the official publication of the Communist Party of Spain (PCE), first published on August 23, 1930, shortly after the fall of Spain’s Primo de Rivera dictatorship. Under the Franco dictatorship the paper was repeatedly suppressed; according to Público, imprisoned PCE militants handwrote miniature, illustrated copies of the paper and smuggled them out of Francoist prisons for clandestine distribution. It returned to open circulation after the PCE’s legalization in 1977, and is currently published as a monthly print magazine alongside a daily news website, based in Madrid. In July 2026, the outlet published its own account of a State Council Information Office-organized seminar in Xinjiang, describing Urumqi as a logistics hub of the “New Belt and Road” — Xinhua separately quoted a Mundo Obrero columnist, identified as Jesús Rodríguez Rojo, praising Xinjiang’s “smart agriculture” during the same trip.
