On Friday, Mexico's government released a copy of the letter that President Donald Trump teased earlier this week as containing more details regarding the recent immigration deal between the two countries.
The letter outlines an agreement -- rather than a deal -- to begin negotiating a future agreement on sharing the responsibility of processing refugee claims of migrants.
Mexico also committed to immediately start examining its laws and regulations to identify any necessary changes to ensure a future agreement.
On Tuesday, President Trump told reporters at the White House that the letter was "one page of a very long and very good agreement for both Mexico and the United States."
The two sides will reconvene in 45 days to determine if Mexico has hit the goals discussed in the deal, and again in 90 days.
