<h1>Mexico president denies formal DEA agreement over 'Project Portero', says only four officers attended a U.S. workshop</h1> Mexico's president denied any formal agreement with the U.S. Drug Enforcement Administration after the agency announced 'Project Portero,' calling the DEA statement premature and asserting no security institutions had signed on; she said only a Texas workshop involving four Mexican police officers had occurred. The administration urged adherence to protocols and stressed it signs agreements with the U.S. government, not individual agencies. Mexican officials said a broader bilateral security pact - framed around sovereignty, mutual trust, territorial respect and coordination without subordination - is near completion, while the DEA characterized the training as a step toward strengthened operational and intelligence cooperation.
