Foreign minister: Mexico 'will not accept' new United States immigration proposals

As Trump issued his warning, Kelly and Tillerson met on Thursday with Mexican ministers who expressed "concern and irritation" over the us president's combative stance on trade and migration ties with Mexico.

"All of a sudden for the first time we're getting gang members out, we're getting drug lords out, we're getting really bad dudes out of this country", Trump reportedly said to the CEOs".

The immigration guidelines are the latest point of tension between neighbours that have also been at odds over Mr Trump's vow to build a wall on the border and his attempts to browbeat Mexico into giving concessions on trade.

Since the earliest stages of his presidential campaign in 2015, Trump has vowed to build a wall along the US border with Mexico as a way to stop illegal immigration and drug trafficking.

Mexico's foreign minister, Luis Videgaray, was clearly incensed by Trump's stance, stating at the outset that he disagrees with America's ramped-up targeting of Mexico, and wants the rights of Mexicans living in the United States to be respected.

On the more narrow issue of immigration, however, treating Mexico like garbage is counterproductive to the Trump administration's supposed goal of reducing undocumented immigration to the United States.

However, people on Twitter pointed out that calling deportations a "military operation" is problematic.

Tillerson acknowledged the disputes that have damaged U.S. -Mexico relations in recent weeks.

The Mexican officials were more outspoken in highlighting their negative feelings toward certain US policies. Kelly said the USA approach will involve "close co-ordination" with Mexico's government.

President Trump promised attendees at the Conservative Political Action Conference outside Washington today that construction of a wall along the southern border is "way, way, way ahead of schedule" and building would "start very soon".

The United States and Mexico have cooperated closely over the past decade.

"Not true", Sean Spicer, White House press secretary, tweeted earlier this month after The Associated Press reported that President Trump's administration was considering mobilizing the National Guard.

But it is unclear whether the U.S. has authority to force Mexico to accept foreigners.

"In a relationship filled with vibrant colors, two strong sovereign countries from time to time will have differences", Tillerson said.

Trump said he wasn't against all the press, just "the fake news media or press".

"There's no mistaking that the rule of law matters along both sides of the border".

Not only is Mexico not going to "pay for the wall", but the new United States administration is discovering that it takes two to tango.
