The US government has imposed restrictions on Mexican fishing vessels from entering US ports in the Gulf of Mexico, following accusations of illegal fishing for red snapper in US waters. Mexico's Secretary of Foreign Relations, Marcelo Ebrard, explained that the incursions were unintentional due to the difficulty in distinguishing the border between the two countries' territorial waters. However, critics suggest that the repeated infringements by Mexican boats imply deliberate fishing in US waters. Since 2014, some Mexican fishermen have been arrested for illegal fishing in US waters over 20 times. This incident highlights Mexico's poor record in enforcing fishing regulations and its failure to implement environmental commitments for sustainable fishing practices, as per the free trade agreement with the US and Canada.
