Mexican President quits meeting after Trump's border wall executive order

Enrique Pena-Nieto has by far the lowest approval ratings in Mexican Presidential polls dating back more than 30 years. His party is headed for a crushing defeat in next year's election as his country continues to be Donald Trump's punching bag.
He was lambasted at home for meeting Trump during the election and earlier this week pleaded for appeasement. The Trump border announcement yesterday was said to take Mexico by surprise.
At some point he will have nothing to lose and decide to go out fighting. This might be a small step in that direction.
In terms of the market, the already-frosty relationship has unwound yesterday's USD/MXN drop and sent the pair to 21.30 from a low today of 20.90.
