US President Donald Trump has said, the deal with Mexico to curb illegal migration opened an era of great cooperation between the two nations, something that they did not see for decades. Mr Trump said this in a tweet.<br />''<br />''On Friday, Washington had announced that it reached an agreement with its southern neighbour to curb illegal migration flows from Central America to the US. <br />''<br />''Under the deal, Mexico will deploy its National Guard throughout the country and, especially, to its southern border and work to dismantle human smuggling.<br />''<br />''<span style="color: #222222;">The United States will also return asylum seekers, crossing its southern border, to Mexico where they will wait for decisions in their cases. The migration deal came just days before new US tariffs on imports from Mexico were supposed to come into force. </span><br />
