On Wednesday, about 200 military policemen, agents of the Immigration Service and the Federal Police in Mexico blocked the roads in front of about 1,000 migrants from South American countries, who were walking on one of the main streets trying to cross the border towards the United States. The operation to stop the progress of this migrant caravan shows how serious the authorities in Mexico are to limit its use as a transit station to the other side of the border. This convoy, which also included women and children, had set off towards the main city of Tapachula in the border region, but security men blocked the roads 11 kilometers from the city. Some of the people who prevented resistance and broke through the security cordon were arrested, and the rest were transported by buses, and a young man was taken to the hospital because he was ill. According to statements by officers in the Immigration Department, about 600-800 migrants will be transferred to the detention center in Tapachula. Recently, Mexico resorted to setting up barriers and checkpoints to stop the flow of migrant convoys that became widespread in 2018 and early this year. They seek to reach the US border, where they submit asylum applications upon their arrival.

Who are the major players and who are the main active forces? Mexican moves to stop the migrants began after the visit of Mexican Foreign Minister Marcelo Ebrard to Washington, in an attempt to dissuade the United States from its intention to increase customs tariffs on Mexican goods, in accordance with the threats of US President Donald Trump, who demanded that Mexico take serious steps to stop the crossing of migrants into the United States. Migrants adopted the idea of convoys last year, which angered Trump. These convoys are considered safer for cross-border travel and less expensive than smugglers. The scenes and pictures of the march sparked a wave of sympathy for them and gave them symbolism. Mexican cities sympathized with the first caravans, but as they continued, they stifled the people, due to the lack of resources to secure the needs of the new arrivals, in addition to the spread of robberies and acts of violence.
