Mexico published an updated list of U.S. products subject to tariffs, including a 5 percent tariff on ham and other pork products.
The government of President Felipe Calderon was infuriated last year when U.S. lawmakers voted to cancel funding for a pilot program begun under U.S. President George W. Bush allowing long-haul Mexican trucks to circulate in the United States.
Under the North American Free Trade Agreement, which took effect in 1994, the United States agreed to open its market to Mexican trucks.
Mexico said the United States was not living up to its end of the deal and retaliated by imposing duties on a long list of U.S. exports, including fruit, vegetables and industrial goods.
In addition to pork, several agricultural and food items were assigned 20 percent tariffs Wednesday, including some cheeses, oranges, grapefruits, chewing gums and ketchup.
Sweet corn was given a 15 percent tariff.
Mexico's Economy Minister Bruno Ferrari said negotiations over the trucking dispute had stalled, forcing Mexico to take new action. He said Mexico would keep revising the list to affect a broader spectrum of goods.
