"And the money they send home helps the Mexican economy."

The Mexican economy has recently shown a number of signs that investors see as positive.

"With a more open Mexican economy, our strategy has had to change."

In 1982, when the Mexican economy collapsed, it had taken almost a decade for growth to return.

The Mexican economy contracted 10.5 percent in the second quarter of this year.

"It means that the Mexican economy is not expanding and so people have had to leave."

Including 1991 data, the Mexican economy has grown by an average 3.8 percent in the last three years, the statement said.

In the third quarter, the Mexican economy fell 1.1 percent.

With such small savings, it is not likely to provide much help for the Mexican economy.

"The great success of the Mexican economy has suddenly been called into question," he said.
