Facing the prospect of new tariffs imposed on all goods sent to the U.S., the Mexican government is proposing to overhaul its asylum rules and deploy thousands of troops to the country's border with Guatemala to curb the unprecedented surge of migrant families journeying to the U.S. -Mexico border.
The US vice-president, Mike Pence, said in Pennsylvania on Thursday that the US was "encouraged" by Mexico's latest proposals but that, so far, tariffs still were set to take effect on Monday.
According to Reuters news reports, the Mexican action in Metapa, the border town, marked the tightening of the government's efforts to put an end to migration flow mainly from Central American, a coordinator with Fray Matias de Cordova, Salva Cruz said.
But despite a shoving match, the authorities managed to force the caravan to a stop.

US border officers apprehended more than 132,000 people crossing from Mexico in May, a third more than in April and the highest monthly level since 2006, reaching what USA officials said on Wednesday were "crisis" levels.
Mexican authorities also blocked 420 migrants in a new caravan, although the group was initially about 1,200-strong, with many suspected of running away before immigration officials stepped in.
The INM said that where applicable, the detained migrants would be "assisted to return to their countries of origin" - its term for deportation.
Two activists from People Without Borders (Pueblo Sin Fronteras), which has helped organise migrant caravans, were arrested on allegations of offering migrants money to enter Mexico illegally.
Federal police have also been deployed to prevent migrants from getting on the train, known as the La Bestia or the Beast, that travels north toward the USA border. Most of the illegal migrants who cross into Mexico from Central America every year are more often than not fleeing from persecution and violence.
