Homeland Security Secretary John Kelly will meet with Mexican government officials in Mexico City over three days this week, according to a department statement issued late Tuesday.

Kelly will be in Mexico Wednesday through Friday to discuss building the U.S.-Mexico relationship while working together to combat transnational criminal organizations, enhance regional security and boost economic cooperation, according to the statement.

The U.S., Mexico and Canada are in the early stages of reforming the North American Free Trade Agreement following President Trump's campaign promise to build a better deal that benefits American workers.

The deal was first created by the Clinton administration in 1994 as a way to ensure no tariffs of goods between the three countries. The three nations had agreed to a 90-day review process of the agreement.

Trump also vowed to build a wall at the southern border and bill Mexico for the project, estimated at $20 billion. Currently, the federal government is considering bids from international companies.
