Mexican pro-government and opposition deputies made on Tuesday a call to the government of President Felipe Calderón to act cautiously and prevent the nationalization of Cemex's assets from straining relations with Venezuela.

Alejandro Landero, of ruling Partido Acción Nacional (PAN), told Efe that regretfully, no deal was made to nationalize Cemex's assets, unlike companies Holcim and Lafarge, which managed to agree on a sale price.

"While there was news since April, this action took us unawares, given the character of the relations that President Calderón has tried to hold with his counterpart, President (Hugo) Chávez," he added.

Landero, a member of the Commission of Foreign Affairs of the Chamber of Deputies, lamented that the price offered to Cemex by the Venezuelan government had not met the expectations of the Mexican firm.
