The staunch defense of coup leader Pedro Castillo has cost Mexican President Andrés Manuel López Obrador the repudiation of the Peruvian Congress. "The unacceptable statements constitute, once again, a violation of the principle of non-interference in matters that are within the domestic jurisdiction of another state," the parliamentary statement said.

The then vice president replaced the leftist leader last December after the attempted self-coup orchestrated by the then president failed. Congress voted by a majority to impeach him and the judges sentenced him to remain in provisional detention for at least a year and a half.
