Overview
- Local activists, indigenous mayo‑yoreme communities and fishers set up a continuous plantón (encampment blockade) after large demonstrations that entered construction areas and began on the weekend of June 6–7, and they continue to bar machinery and workers from the site.
- Proman GPO says the blockade is disrupting operations, affecting about 3,000 workers on the project and local suppliers, and has temporarily stopped some construction activities.
- Opponents and scientists warn the complex threatens the Bahía de Ohuira Ramsar area by raising bay temperatures from cooled reactor discharge, harming mangroves and fisheries, and posing risks from potential ammonia releases.
- Promoters and several agricultural groups defend the investment as a major foreign project backed by German financing that would produce large volumes of ammonia, lower fertilizer imports and create jobs during construction and operation.
- Protesters have demanded federal action and a presidential meeting while SEMARNAT has said it will listen; the dispute also carries legal weight after a 2022 Supreme Court order on adequate indigenous consultation and has drawn attention at the German embassy.
