US Republican presidential candidate Donald Trump has accepted an invitation from the Mexican president to visit the country this week.
Mr Trump tweeted that he was looking forward to meeting President Enrique Pena Nieto, who has also invited Democratic candidate Hillary Clinton.
I have accepted the invitation of President Enrique Pena Nieto, of Mexico, and look very much forward to meeting him tomorrow.— Donald J. Trump (@realDonaldTrump) August 31, 2016
The meeting will come just hours before Mr Trump is due to outline his proposals to crack down on illegal immigration in a speech in Arizona tomorrow.
Mr Trump has controversially called Mexican migrants "criminals" and "rapists" during his campaign.
He has also pledged to build a wall between the two countries and has steadfastly demanded that Mexico pay for the wall.
Mr Pena Nieto has publicly voiced scepticism about Mr Trump.
There has been no word from the Clinton campaign as to whether Mrs Clinton will accept the Mexican leader's invitation.
