Matteson Ellis was quoted regarding Mexico's recently passed anti-corruption rules and the impact on business. The new anti-corruption program comes at a time when public spending fairness faces one of its biggest tests. With the opening of the oil industry to foreign investment, there will be billions of dollars of contracts with international companies, and for those investing in this environment, the new rules mean less risk, Ellis said.

"This will be a highly significant development for the international business community. It gets directly at the issue of impunity. No longer is a U.S. company forced to tell its Mexican business partner, you've got to comply with this law in the U.S. Now they can say, you need to comply with your own laws," he said.
