A pipeline is planned to carry natural gas from Tucson to the port city of Mazatlan in Mexico, Mexican president Enrique Peña Nieto announced Tuesday.

The $460 million project will be headed by Mitsui Corp., a Japanese firm, the Mexican president's office said in a statement.

The pipeline will be able to carry 770 million cubic feet of gas per day. The statement did not say who would build the U.S. end of the pipeline.

Mexico's gas network already includes a number of active connections with the United States.
