MEXICO CITY (Reuters) - Mexican President Enrique Peña Nieto on Wednesday said Mexico will seek to negotiate issues including trade, security and migration with the incoming U.S. administration of Donald Trump, but would not pay for a U.S. border wall.

Peña Nieto, speaking to an assembly of foreign diplomats, said he would continue to promote free trade integration in North America.

Mexico would invest in a more secure border but not a wall, he added, but the U.S. shared responsibility on immigration and should work to stop the southward flow of illegal weapons.
