"If the measures we are proposing are not successful, we have to discuss with the United States and with other countries, like Guatemala, Panama and Brazil", Ebrard said.
Trump, speaking to the media before leaving for a trip to Iowa, didn't provide details of the nature of the agreement.
"Starting from today, and in the coming days, the deployment is going to progress rapidly", Ebrard said in a news conference with Mexican President Andres Manuel Lopez Obrador, according to Reuters.
Mexico's National Guard is a newly formed force tasked with policing rising insecurity. He said that if migration into the USA isn't reduced, the White House wants his country to accept asylum applications from Central Americans instead of allowing them to apply across the border, a measure that would require the approval of Mexico's senate.
Mr Ebrard added that Mexico had also dismissed U.S. demands to see the country commit to "zero migrants" crossing its territory.
If, after 45 days, the U.S. government "determines at its discretion" that the results aren't enough, the document says, 'the Government of Mexico will take all necessary steps under domestic law to bring the agreement into force'.
Mexican foreign minister Marcelo Ebrard has gradually announced more commitments his country made to stave off Trump's threat of tariffs, noting Tuesday Mexico must improve its border infrastructure with Guatemala as part of the agreement.
US border officials apprehended about 133,000 people at the border in May, triple the amount from a year earlier though still below historic highs.
Nice try. If Mexico had truly agreed to implement many of these measures in December, then why had they not been implemented six months later?
The U.S.is on pace for about 900,000 apprehensions at the border this fiscal year - levels that border officials have said is a crisis that's straining resources - but the future is hard to predict.
Mexico has now agreed on taking steps to stop the inflow of migrants to US so as to avoid the trade tariffs as threatened by US President. While talking with reporters Monday, the president brandished a sheet of paper and identified it as the agreement in question - but refused to share details of what it contained.
U.S. President Donald Trump participates in a roundtable discussion on immigration and border security at the U.S. Border Patrol Calexico Station before visiting the U.S. -Mexico border in Calexico, California, U.S., April 5, 2019.
In return, the Trump administration said they were committed to working toward accelerating the processing of asylum claims as well as finalize removal proceedings as quickly as possible.
