Some 100,000 farmers marched January 31 in Mexico City to protest the lifting of tariffs on corn and other agricultural imports from the United States under the North American Free Trade Agreement. They called on the government to renegotiate the trade treaty with the United States and Canada, which has made it increasingly difficult for Mexican peasants to survive on the land due to their country’s unequal trade relations with the two imperialist powers. Protests also took place in other Mexican cities.
