Castro spoke informally with a small group of newsmen Friday at midnight while making an unexpected tour of the Mexican industrial exposition inaugurated a few hours earlier. The Cuban leader said however that he doubted very much if his trip to Mexico could be made this year because of the many matters related to the preparations for the first Cuban Community Party Congress to be held here in November. In turn Mexico's President Luis Echeverria is expected to visit Cuba having accepted an invitation some time ago, although the date has not yet been set. Castro warmly praised Echeverria last night for the cordial attitude which he as president has shown toward Cuba and said that relations between the two countries are better than ever. Castro also said that the Cuban Government will participate in the Latin American Economic System, an integrational organization which excludes the United State and whose creation was proposed by Echeverria and his Venezuelan colleague, Carlos Andres Perez. -END-
