Earlier at the moment Mexican president Enrique Pena Nieto has stated he won’t attend a deliberate assembly along with his US counterpart Donald Trump.
This comes hours after Mr Trump tweeted that the January 31 assembly in Washington needs to be cancelled if Mexico won’t pay for his deliberate US-Mexican border wall.
Mr Pena Nieto’s message on Twitter ended days of uncertainty about what he would do.
Earlier, Mr Trump had tweeted that if Mexico is unwilling to pay for a wall alongside the US border, “then it will be higher to cancel the upcoming assembly”.
