Trump Says Build US-Mexico Wall or he'll Seal Border

President Donald Trump threatened Friday to seal the US-Mexico border "entirely" if Congress does not approve billions of dollars in funding for a wall, reports AFP. 

In a burst of early morning tweets, the president said the alternative to funding his controversial wall project would be total separation from Mexico -- including making US car companies pull out their factories based on the other side of the frontier.

The threat yet again upped the ante in a political row that has led to a partial shutdown of the US government and seems set to dominate the start to the third year of Trump's presidency.

"We will be forced to close the Southern Border entirely if the Obstructionist Democrats do not give us the money to finish the Wall," Trump tweeted.

Trump said he would then take US-Mexican relations back to the days before the NAFTA agreement opened free trade across Canada, Mexico and the United States.

That would "bring our car industry back into the United States where it belongs," he said.

It was not clear how separating the two huge neighbors would work. Bilateral trade totaled an estimated $615.9 billion in 2017, according to US government figures.

Neither did Trump make any mention of the new free trade agreement, known as the USMCA, which he only recently signed with the two neighboring countries to replace NAFTA and which he has repeatedly praised as a huge boost for American commerce.

In Mexico, President Andres Manuel Lopez Obrador sidestepped Trump's threat, telling journalists: "We don't want to be imprudent and we don't think we should get into this."
